Our thick transparent PE liners are crafted from premium high and low-density polyethylene materials. Designed as versatile inner packaging solutions, they add reliable moisture, dust and leak protection for all kinds of outer packaging, including cartons, plastic drums and woven sacks. Thanks to their dependable performance, these liners fit packaging and storage needs across almost all industries.
We only use brand-new pure polyethylene raw material for production. The material is completely odorless and fully compliant with food packaging hygiene standards. No recycled or inferior materials are added, so it easily meets the strict hygiene requirements for food and pharmaceutical packaging applications.
We boost the overall durability of these liners by upgrading the film thickness. This simple yet effective upgrade greatly improves tear strength and wear resistance, offering solid protection for goods during long-distance transportation and repeated handling. The transparent and semi-transparent finish also brings huge convenience for daily management. Staff can clearly check internal contents without opening the outer package, making stock counting and routine quality inspections much simpler and more efficient.
The bag opening works perfectly with heat sealing processing. A tight heat-sealed closure further locks out moisture and dust, delivering excellent leak-proof and moisture-proof performance for long-term storage and transit.
We supply two mainstream styles: flat-bottom and square-bottom designs. The square-bottom version stands steadily on its own, which makes manual and machine loading, unloading and filling far more convenient for on-site operation.
These PE liners cover a very wide range of practical applications. In the food industry, they are commonly used for milk powder, seasonings, hot pot bases, food additives and various dried ingredients. Great moisture resistance and fresh-keeping performance effectively preserve food quality and safety throughout storage.
For chemical materials and general hazardous goods, the liners work well for fine chemical raw materials, engineering plastics, and various powder and granular products. They effectively stop fine powder leakage and avoid material waste and workshop contamination.
Electronics and precision instrument industries also rely on these liners for packaging semiconductors, circuit boards and other delicate components. The clean, stable internal environment protects precision parts from dust and minor abrasion damage.
In the pharmaceutical sector, they serve as qualified inner packaging for pharmaceuticals and medical devices, maintaining strict hygiene and safety standards. Additionally, they are widely used in the building materials and feed industries for dry powder materials and feed additives, providing steady dust and moisture protection for dry bulk goods.
We offer flexible specifications and full customization support. Standard stock colors include transparent, white, blue and black. Film thickness and overall weight can be adjusted freely to match your actual usage scenario. These liners fit diverse packaging capacities, ranging from small 25kg packages all the way up to 1000kg ton bag inner liners.
All details can be tailored according to your order volume, including exact dimensions, film thickness, special colors and custom printing. We adjust every parameter to create a targeted packaging solution for your goods.
To help you pick the most suitable liner for your needs, we suggest confirming a few key details in advance. First, clarify your product attributes - such as whether you need food-grade safety or extra functions like anti-static performance - to lock in the right material standard. Second, choose a proper film thickness based on your product weight and transportation conditions, ensuring the bags are durable enough for your entire logistics process.
