Made of reliable PE material, these inner liners do a great job keeping air and moisture away from your goods. They work well as inner packaging for dried food, grains, various powder and granular products, hardware accessories, electronic parts and chemical raw materials for daily packing and storage.
The PE film is thick and flexible, so it does not tear easily during handling and shipping. We have two common styles for customers to pick from: flat-open square bottom and flat-open straight tube. Transparent is our standard color, which makes it easy to check the inside goods directly.
We have different thickness options, from standard to thickened grades. Thicker material holds heavier weight better and resists punctures more effectively. The flat opening supports various sealing methods. You can use tape, cable ties or heat sealing machines according to your own working process. We have all regular sizes in stock and can customize special sizes to match your packaging needs.
These liners are waterproof, moisture-proof, dust-proof and leak-proof. With good sealing performance, they can keep your products dry, tidy and free from contamination during long-term storage and transportation.
The biggest difference between our moisture-proof liners and ordinary plastic bags is the barrier structure and real moisture resistance. Normal bags only offer simple coverage with no professional barrier layer. Our liners adopt multi-layer composite structure, with food-grade PE film, aluminum foil or aluminized layer added to block moisture effectively.
The actual test results speak for themselves. After 30 days in an 85% high humidity environment, goods packed in our liners stay totally dry. In comparison, products in ordinary film bags will easily get damp.
We also pay extra attention to edge and bottom sealing quality. All edges are tightly heat sealed, and the folded bottom uses double-line sealing craft. This effectively prevents moisture from penetrating through tiny gaps at the seams.
