IV. Core Functions & Advantages (In-Depth Analysis)

1. Triple Protection System for Comprehensive Protection of Sensitive Components

• First Layer: Surface Static Dissipation: The anti-static coating can quickly conduct away the frictional static electricity on the bag surface, avoiding static dust adsorption or electrostatic field formation, and reducing the risk of component surface pollution and electrostatic induction.
• Second Layer: Internal Static Isolation: The high-insulation inner PE layer isolates external electrostatic fields, preventing internal products from being damaged by induced static electricity, especially suitable for products susceptible to static electricity such as PCB boards and optoelectronic modules.
• Third Layer: Electromagnetic Shielding Protection: The metal shielding layer can weaken external electromagnetic interference (EMI), prevent electromagnetic radiation from interfering with sensitive circuits, and protect signal integrity and component stability.

2. Self-Sealing Design, Convenient and Efficient to Use, Suitable for Bulk Scenarios

• Heat-Seal Free Operation: Built-in bone strip self-sealing mouth, no additional heat-sealing equipment required, a single person can quickly package, greatly improving workshop turnover and packaging efficiency, suitable for mass production scenarios.
• Reusable Opening and Closing: The self-sealing strip fits tightly, can be reused multiple times, facilitating quality inspection, sampling inspection and customer unpacking, reducing packaging costs.
• Sealed, Moistureproof and Dustproof: The self-sealing strip adopts a non-slip tooth design with good sealing effect, which can effectively isolate moisture and dust, avoid metal pin oxidation and component short circuit due to dampness, and extend product storage life.

3. High Toughness and Durability, Suitable for Different Products and Transportation Scenarios

• Puncture and Tear Resistance: The multi-layer composite structure provides excellent mechanical strength, which can withstand the puncture impact of PCB edges and LED strip pins, and is not easy to break and leak goods.
• Strong Flexibility: The bag body can be bent and folded without being brittle, suitable for products of different shapes, reducing collision damage during transportation.
• Scratch and Wear Resistance: The outer PET layer is smooth and wear-resistant, not easy to scratch, protecting the product appearance from wear and improving the shipping image.

4. Flexible Customization to Meet Diversified Wholesale Needs

• Size and Specification Customization: Multiple specifications are available. Common sizes include 10×15cm, 15×20cm, 20×30cm, 25×35cm, etc. The length and width can be customized according to customer product sizes.
• Style Selection: Optional styles include flat bags, self-sealing bags, zipper bags, shielding bags, grid conductive bags, etc., to meet different protection and use needs.
• Thickness Customization: The thickness can be adjusted according to the protection level, ranging from 0.05mm to 0.2mm, to balance cost and protection performance.
• Printing Customization: Supports single-color/multi-color printing, which can print brand logos, anti-static warning signs, product models, batch numbers, QR codes, etc., to realize branding and traceability management.

V. Application Scenarios & Industries

• Electronic Manufacturing Industry: Production turnover and packaging of electronic components such as PCB circuit boards, LED strips, driving power supplies, capacitors, resistors and connectors.
• Optoelectronic/Communication Industry: Anti-static packaging of electrostatically sensitive accessories such as optical modules, sensors, camera modules and communication modules.
• Warehousing and Logistics: Finished product warehouses, raw material warehouses, e-commerce and courier packaging of electrostatically sensitive products, avoiding static and collision damage during transportation.

VII. Usage & Storage Precautions

·Before use, check whether the bag body is damaged and the self-sealing strip is intact; do not use invalid bags.

·Store in a dry and ventilated environment with a temperature of 15~30℃ and a humidity of 40%~60%; avoid direct sunlight and contact with chemicals.

·Keep away from sharp objects to prevent the bag body from being punctured and affecting the protective effect.

·Seal the self-sealing bag in time after opening to avoid moisture and dust affecting performance.

·When packaging sharp components such as PCB boards, avoid direct contact between the sharp edges and the bag body to prevent puncture; you can add buffer materials if necessary.
