pavelets Industrial light-proof bags (also known as metal silver lightshielding bags, PE light-proof bags) are special packaging materials used in the chemical, metal, and electronic industries. They are mainly used to pavelets prevent ultraviolet and visible light damage sensitive items. Here are the relevant product information and technical points: Material and structure‌ Aluminum foil layer‌: Most light-proof bags use aluminum foil as the light-blocking layer. Its electromagnetic shielding performance can block external interference and has the characteristics of moisture-proofing and oxygen-proofing, making it suitable for long- storage of humidity-sensitive items‌

Composite design‌: Common structures include multi-layer composites (such as PET/AL/PE), where the outer pavelets PET layer strength, the middle aluminum foil layer blocks light, and the inner PE layer ensures sealing, balancing functionality and durability‌ 1. Typical product recommendation Black light-proof bag Material: 1-100丝 thickened PE, waterproof and dustproof Features: Non-transparent sealed design, suitable for the storage of chemical raw materials a light-proof manner. Silver anti-static anti-UV bag‌

Material: PE anti-static anti-aging agent light-proof Features:-sided anti-ultraviolet, suitable for high-end scenarios such as optical components and medicinal materials. Metal PE light-proof bag‌ Chemical electronic‌:pavelets Light-sensitive liquids, metal materials for light-proof storage‌ Electronic industry‌: Chips, circuit boards for anti-static   light-proof double protection Laboratory light-proof bag‌: Temporary packaging of photosensitive reagents, samples.
