25kg Heavy-Duty Aluminum Foil Bags for PBT/PET Modified Pellets

July Mon , 2026

Polyester engineering plastics serve as key substrates for home appliances, automobiles and electronic connectors, including flame-retardant PBT, glass-filled PBT, toughened PET, PET blends, PET master-batches and polyester alloys. They are highly susceptible to hydrolysis. Under humid and hot conditions, molecular chains break down, resulting in reduced product strength, cracking and dimensional deviation. Condensation inside shipping containers, humid coastal storage and hot summer weather accelerate deterioration, making polyesters notoriously difficult to store.

XCGS 25kg aluminum foil bags are dedicated moisture-proof packaging for modified polyesters. The 4-layer aluminum-plastic composite structure features low water vapor transmission rate, effectively resisting condensation during sea transport and ambient humidity penetration to maintain consistent dryness of PBT and PET pellets. A nylon puncture-resistant layer withstands abrasion and piercing from rigid and glass-filled polyester pellets to avoid leakage and seal failure. The fully light-shielded aluminum foil prevents photo-aging and yellowing, ensuring consistent appearance and performance of raw materials.

Heat sealing, vacuum packaging and custom shipping mark printing are available. The standard 25kg size fits container loading and palletized shipment, complying with customs and transport standards for exports to Europe, America, Southeast Asia, the Middle East and other regions. Numerous polyester compounders and engineering plastic traders adopt our bulk bags to reduce commercial risks such as ocean freight returns, material scrap-page and defective batches, supporting long-term storage and cross-border transportation of polyester feed-stock for home appliances, automotive and precision electronic components.

With long-term experience in chemical and new energy export packaging, XCGS fully understands storage and shipping challenges of polyester engineering plastics. Supported by large-scale smart manufacturing across six production bases, we mass-produce puncture-resistant, anti-condensation, high-barrier 25kg aluminum foil bags tailored for hydrolysis-prone PBT and PET pellets. Custom export marks, vacuum packaging and batch traceability are supported. Global port delivery services cover more than 100 countries worldwide, making us a reliable foreign trade packaging partner for polyester engineering plastic manufacturers.
