In today's rapidly iterating high-end manufacturing industry, electrostatic discharge (ESD) has become a "hidden killer" that threatens sensitive products such as precision electronic components, semiconductor chips, aerospace components, etc. According to industry data, the scrap rate of electronic components caused by electrostatic damage exceeds 65%, directly causing huge economic losses. As a core protective material with controllable cost, strong adaptability, and environmental compliance, anti-static packaging paper has deeply penetrated into many highly sensitive fields such as electronic manufacturing, semiconductors, new energy, aerospace, etc., becoming a key barrier to ensure the safety of products throughout their lifecycle. With the tightening of global electronic supply chain standards, the upgrading of advanced semiconductor processes, and the promotion of "dual carbon" policies, anti-static packaging paper is accelerating its transformation from basic protection to high-performance, multifunctional, green, and intelligent directions. Its technological iteration and industrial application level are directly related to the development quality of high-end manufacturing industry.
1、 Core definition and protection principle: Cracking the underlying logic of electrostatic damage
Anti static packaging paper is a functional packaging material that is processed through special techniques to impart static dissipation or shielding functions to paper. It can suppress static electricity generation, quickly dissipate static charges, and avoid damage to sensitive products caused by static electricity accumulation, such as breakdown, oxidation, and interference. Compared with ordinary packaging paper, its core advantage lies in the dual performance of physical protection and electrostatic protection, as well as the characteristics of recyclability, easy processing, and wide adaptability, which can achieve customized production according to downstream scene needs.
Its anti-static principle is mainly divided into two core paths, adapted to different protection needs:
One is the principle of electrostatic dissipation, which involves adding anti-static agents (such as environmentally friendly soy based coatings, conductive polymer masterbatch, etc.) or implanting conductive fibers into the paper substrate to construct a uniform conductive path. This slowly disperses the static charges generated on the packaging surface or inside to the ground or air, avoiding the accumulation of charges and the formation of high potential differences, thereby eliminating the phenomenon of electrostatic discharge. The surface resistance of such products is usually controlled between 10 ⁶Ω~10 ¹¹ Ω, which can achieve rapid dissipation of charges and avoid the impact of instantaneous discharge on sensitive components. It is currently the most widely used type, such as the anti-static sulfur free paper commonly used in the semiconductor industry, which adopts this principle.
The second is the principle of electrostatic shielding. By compounding conductive materials such as metalized films and graphene on the surface of paper, a shielding layer similar to a Faraday cage is formed, which can prevent external electrostatic fields from penetrating the interior of the packaging and isolate and dissipate the static charges generated inside the packaging. It is suitable for scenarios with extremely high requirements for electrostatic protection, such as the packaging of wafers, high-end chips and other products, and can effectively resist the interference of external electrostatic discharge on internal products.
It is worth noting that the protective performance of high-quality anti-static packaging paper has temperature and humidity stability. Within the temperature range of 10-35 ℃ and relative humidity range of 30% -70%, the surface resistance change rate is ≤ 30%, ensuring stable protection in different storage and transportation environments. This is also one of the core characteristics that distinguishes it from ordinary anti-static coating paper.
2、 Classification and core process: Product system adapted to diverse scenarios
With the refinement and upgrading of downstream application scenarios, anti-static packaging paper has formed a diversified product system. According to the protection level, substrate type, and process differences, it can be divided into three mainstream categories. Each type of product has its own focus on performance and application scenarios, covering the full scene protection needs from ordinary electronic components to high-end semiconductors
（1） Classified by protection level
1. Ordinary anti-static packaging paper: mainly used for electronic components with low static sensitivity, such as resistors, capacitors, and ordinary circuit boards. The surface resistance is 10 ⁹Ω~10 ¹¹ Ω, and the electrostatic half-life is ≤ 2s. It can effectively suppress frictional electrification, meet basic static protection needs, and has low cost. It is widely used in the packaging field of consumer electronic accessories. Its production process is relatively simple, often using surface coating with ordinary anti-static agents, suitable for batch packaging scenarios.
2. Static dissipation packaging paper: The core is used for products with moderate static sensitivity, such as precision sensors, vehicle electronic components, communication modules, etc. The surface resistance is 10 ΩΩ~10 ΩΩ, the static half-life is ≤ 1s, the charge dissipation speed is faster, and it has certain anti dust and anti-corrosion properties. Some products use environmentally friendly coatings such as soy based coatings, which balance protective performance and environmental requirements. They are recyclable and can be repurposed, in line with the "dual carbon" trend.
3. Electrostatic shielding packaging paper: specially designed for products with extremely high electrostatic sensitivity, such as semiconductor wafers, chips, aerospace components, etc., with a surface resistance of ≤ 10 ⁶ Ω, it has excellent electrostatic shielding and charge dissipation capabilities, can resist external strong electrostatic field interference, and can avoid static electricity accumulation inside the packaging. These products often use a composite process of "substrate+conductive coating+shielding layer", and some also incorporate new materials such as graphene and carbon nanotubes to improve protection accuracy and meet ISO Class 4 or higher cleanliness standards.
（2） Classified by substrate type
1. Kraft paper based anti-static packaging paper: Using kraft paper as the base material, it has good mechanical toughness and durability, with a durability strength of ≥ 1600kPa, suitable for bulk shipments scenarios, and is currently the type with the highest market share. By 2025, it will account for 37% of the global market. It is compatible with environmentally friendly anti-static coatings and is commonly used for outer packaging of electronic components, inner lining of turnover boxes, etc., balancing protection and load-bearing requirements. It is widely used in fields such as electronic manufacturing and logistics turnover.
2. Sulfur free anti-static packaging paper: Using high-purity wood pulp raw materials, the sulfur content is controlled below 50ppm through the patented process of "chlorine free bleaching+low-temperature desulfurization", which is far superior to the EU standard. At the same time, it has stable anti-static performance, with surface resistance stable at 10 ⁶~10 ¹¹ Ω and electrostatic decay time ≤ 0.5s. It is mainly used for semiconductor chips, wafers and other products highly sensitive to sulfur elements, which can prevent conductive failure caused by sulfur corrosion and reduce the probability of oxidation failure from the industry average of 18% to below 0.1%. It is one of the core protective materials in the semiconductor industry.
3. Composite substrate anti-static packaging paper: composed of two or more composite substrates, such as kraft paper and conductive pearl cotton composite, paper and metalized film composite, etc., with multiple properties. For example, the outer layer of 400g anti-static kraft paper provides physical protection and basic anti-static ability, while the inner layer of conductive pearl cotton provides buffering and enhanced anti-static effect, suitable for the full process protection of circuit boards, capacitors, resistors and other products. Some products are also equipped with anti-static warning signs and humidity indicator cards to improve usability.
（3） Core production process
The performance of anti-static packaging paper depends on the degree of refinement of the production process. Currently, mainstream processes are mainly divided into three categories and are upgrading towards environmental protection and refinement:
1. Coating process: Uniformly coating anti-static agents (water-based, oil-based, or powdered) on the surface of paper, drying and curing to form an anti-static coating, is currently the most widely used process. The advantage lies in the simple process, controllable cost, and the ability to adjust the coating thickness and anti-static agent concentration according to demand, adapting to different protection levels; The disadvantage is that the coating is prone to wear and tear, and the anti-static performance may deteriorate after long-term use, so it is often used for short-term protection or low demand scenarios. In recent years, environmentally friendly coatings (such as soy based coatings) have gradually replaced traditional coatings. These coatings are free of harmful compounds, recyclable, and can be repurposed. They also have more stable protective performance in low humidity environments, with heat resistance reaching over 200 ℃, making them suitable for high-end scene requirements.
2. Immersion process: The paper is completely immersed in an antistatic agent solution, allowing the antistatic agent to penetrate into the interior of the paper. After drying, it forms a product with antistatic properties both inside and outside. Compared with the coating process, its anti-static performance is more durable, uniform, and less prone to wear. After 10 washes or frictions, the electrostatic half-life is still ≤ 5s, and the surface resistance still meets the standard requirements. It is suitable for long-term storage and repeated turnover scenarios, such as the turnover packaging of semiconductor wafers, but the process complexity is higher and the cost is relatively high.
3. Mixing process: Conductive fibers (such as carbon fibers, metal fibers) or conductive masterbatch are uniformly mixed with pulp, and then processed through copying, forming, drying, and other processes to produce a "plant in" protection. It has the most stable anti-static performance and no risk of coating peeling, which can avoid dust pollution. This type of product has a surface roughness of ≤ 0.1 μ m and a dust particle count of ≤ 3 per square meter, meeting the Class 100 cleanliness standard. It is suitable for scenarios such as semiconductors and medical equipment that require extremely high cleanliness. At the same time, it has excellent physical properties, with a tensile strength of over 3.0kN/m, and can be folded 200 times without cracks or pilling. It is suitable for packaging complex shaped products.
3、 Core performance indicators and testing standards: key to ensuring the reliability of protection
The protective effect of anti-static packaging paper needs to be verified through strict performance testing, and its core performance indicators directly determine the scope of adaptation scenarios. Currently, the industry has formed clear domestic and international standards to ensure the uniformity and compliance of product quality.
（1） Core performance indicators
1. Surface resistance: The core indicator for measuring the static dissipation ability of paper. Different protection levels correspond to different resistance ranges. Ordinary anti-static paper has a resistance range of 10 ⁹Ω~10 ¹¹ Ω, static dissipation type has a resistance range of 10 ⁶Ω~10 ⁹ Ω, and static shielding type has a resistance range of ≤ 10 ⁶ Ω. It needs to be stably controlled in the corresponding range to ensure that the charge can dissipate quickly without producing instantaneous discharge shock.
2. Electrostatic half-life: refers to the time required for the static charge on the surface of the paper to decay to half of its initial value, which is the key to measuring the speed of static dissipation. The smaller the value, the better the protective effect. The industry standard requires ordinary anti-static paper to be ≤ 2s, and high-end products can reach ≤ 0.5s. Some products that use new conductive materials have better static attenuation speed and can quickly eliminate static charges generated by friction.
3. Electrostatic voltage: including frictional electrification voltage and induced electrification voltage, frictional electrification voltage ≤ 500V, induced electrification voltage ≤ 1000V, can avoid high potential static electricity caused by friction and induction, and prevent breakdown of sensitive components. Some high-end products can control the frictional electrification voltage below 200V, adapting to the stringent requirements of advanced semiconductor processes.
4. Stability indicators: including temperature and humidity stability and durability. Temperature and humidity stability requirements are within the range of 10-35 ℃, relative humidity of 30% -70%, and surface resistance change rate ≤ 30%; Durability requirements: After 10 washes or rubs, the anti-static performance still meets the standard, ensuring stable protection in different environments and usage scenarios.
5. Auxiliary performance indicators: Depending on the application scenario, it is also necessary to meet requirements such as cleanliness, sulfur free, dust-free, and high temperature resistance. For example, sulfur free paper for semiconductors with a sulfur content of ≤ 50ppm and a cleanliness level of Class 100; High end products need to have high temperature resistance, able to withstand short-term high temperatures of 230 ℃, and meet the immediate packaging needs of semiconductor devices after drying; Some products also need to meet the requirements of low ion pollution, with Na+, Cl - and other precipitable ions having a content of less than 1.0 μ g/cm ² to prevent chemical pollution.
（2） Core testing standards
At present, the testing of anti-static packaging paper follows dual standards both domestically and internationally to ensure that the product is suitable for the needs of different regions and industries
1. Domestic standards: mainly including SJ/T 11495-2016 "General Specification for Anti static Packaging Materials for Electronic Industry", GB/T 14437-2013 "Evaluation of Electrostatic Properties of Textiles Part 1: Static Voltage Half Life", GB/T 22042-2019 "Surface Resistance Test Method for Anti static Performance of Clothing", etc., which clarify the performance requirements, testing methods and qualification standards of anti-static packaging materials, and are the core basis for production and testing of domestic enterprises.
2. International standards: mainly including ANSI/ESD S20.20, ANSI/ESD S541, MIL-PRF-3420G, etc. Among them, ANSI/ESD S541 specifies the electrostatic shielding test method, which evaluates the shielding effect by applying discharge to the outside of the packaging, detecting internal voltage changes; MIL-PRF-3420G has developed standards for dual performance of corrosion prevention and electrostatic dissipation, suitable for high-end fields such as aerospace and military. In addition, the EU's REACH and RoHS 2.0 certifications are also core compliance requirements for exported products, ensuring that they do not contain heavy metals, harmful compounds, etc.

The shape and specifications can be customized according to the size of the components, and some products also need to have printing function for labeling product information, warning signs, etc. With the upgrading of consumer electronics towards slimness and precision, the requirements for the cleanliness and anti-static stability of anti-static packaging paper are constantly increasing, promoting the upgrading of products to the mid to high end.
（2） Semiconductor field
The semiconductor industry is the fastest-growing application scenario for anti-static packaging paper, with an expected compound annual growth rate of 12% from 2025 to 2035. With the continuous reduction of chip size and the upgrading of advanced processes, the electrostatic tolerance threshold of some devices' HBM has been lower than 30V, which requires extremely high anti-static accuracy, cleanliness, and sulfur free packaging materials. Anti static packaging paper is mainly used for the full process protection of wafer, chip, and semiconductor module production, storage, and transportation, such as sulfur free anti-static paper, shielding anti-static paper, etc., which can eliminate problems such as electrostatic breakdown and sulfur corrosion, and reduce product scrap rate. For example, after a new energy semiconductor manufacturer switched to high-end anti-static and sulfur free paper, the chip static breakdown rate decreased from 5.2% to 0.08%, the PCB board oxidation scrap rate decreased from 4.5% to 0.05%, and the annual cost savings exceeded 3.4 million yuan.

The demand for new energy (mainly power batteries and photovoltaic modules) is growing rapidly, accounting for 17.5% of the domestic market by 2025, becoming a new growth pole in the industry. The electrodes, cells, and other components of power batteries are sensitive to static electricity and need to have flame retardancy, temperature resistance, and other properties. Therefore, anti-static packaging paper needs to balance static electricity protection with flame retardancy and temperature resistance. Some products also need to have reusable functions to meet the closed-loop recycling needs of power batteries; The precision electronic components of photovoltaic modules also require anti-static packaging paper for protection to avoid static interference affecting the performance of the modules. With the expansion of the new energy industry, the demand for high-performance and green anti-static packaging paper will continue to increase.
