Comprehensive analysis of bangkok-portielded light packaging bags, core functions of light protection, bangkok-port PE black self-sealing bags: achieve low light transmittance (＜5%) thickening PE material (usually ≥12 denier), suitable for sensitive items such as pharmaceuticals, cosmetics, etc. that need strict light protection15. Alum foil shielding bags: combined with aluminum foil layer and anti-static coating, it has dual protection (light shielding electromagnetic shielding), used for packaging electronic components bangkok-port chips and other precision devices78.
Sealed moisture-proof The zipper seal design can isolate air and moisture, supplement by multi-layer composite structure (such as PEVA/aluminized film), to achieve waterproof and moisture-proof functions, extend the shelf life of food, chemical raw56.
Physical protection
Some of the aluminum-coated bangkok-port composite bubble bags have the characteristics of shock absorption and shock resistance protecting fragile items during transportation7.
Second, the mainstream material classification
Type characteristics Application scenarios
PE black shielded bag Low cost, good flexibility, light transmitt controllable (0.1%-5%) Pharmaceutical shielded light packaging bags, sealed privacy items15
Aluminum foil composite bag Full shading (10% non-transparency), anti-static, tear-resistant, can customize shielding efficiency (≥60dB) bangkok-port electronic components, equipment protection78
bangkok-port White cowhide paper bag Environmental and degradable, the inner layer is covered with PE/aluminum foil film to enhance the barrier, light transance ＜10% Food, tea and other natural products that need to be shielded6
Third, the typical application scenarios of shielded light packaging bags
armaceutical field: Black shielded bags are used for infusion bags, raw and auxiliary material packaging of drugs, avoiding ultraviolet rays causing component decomposition5.
[provor_city] Electronics industry: Aluminum foil shielding bags are used to package LED light beads, integrated circuits, and prevent electronic drift caused by light7.
Food preservation: Cowhide paper composite aluminum foil bags are used to store coffee beans, nuts, etc., to block light and delay the oxidation and spoilage of oil
