LDPE Film Manufacturers
LDPE films are generally made using both blow moulding and cast processes. Cast polyethylene film is of uniform thickness but is rarely used due to its high price. Blown polyethylene film is made from blow moulded grade PE pellets blown by a blow moulding machine and is the most widely used as it is less expensive. LDPE film is a translucent, glossy, softer film with excellent chemical stability, heat sealability, water and moisture resistance, freeze resistance and can be boiled in water.Manufacturer of standard and custom stretch, shrink, bundling, multilayer, Surlyn® and skin packaging film. Made from LDPE Film. Capabilities include bag filling, labeling and contract packaging. Secondary services such as supply chain management, repair, rebuild and preventative maintenance provided. Prototype and low to high volume production runs available

(LDPE), whose main drawback is its poor barrier to oxygen, is commonly used as the inner film of composite flexible packaging materials and is also one of the most widely used and largest plastic packaging films, accounting for about 40% or more of plastic packaging film consumption.
As polyethylene molecules do not contain polar groups, and high crystallinity, the surface free energy is low, therefore, the film has poor printing performance, poor adhesion to ink and adhesive, so the surface treatment is required before printing and lamination.
- The film is slightly opalescent and transparent and soft. The strength is smaller than that of HDPE, while the impact strength is greater than that of HDPE.
- Cold, low temperature and higher temperature resistance. Thicker films can withstand the sterilisation process by immersion in hot water at 90°C.
- Moisture resistance is better, chemically stable and insoluble in general solvents.
- There is a large air permeability, so when used as oxidation-prone food packaging, the storage period of its contents should not be too long.
- Poor grease resistance, products can be slowly dissolved up. Packaging containing grease food, long storage will make the food appear harsh taste.
- A long period of ultraviolet light and heat will be aging, affecting its physical properties and dielectric properties.
- Melting point of 110 ~ 115 ℃, processing temperature of 150 ~ 210 ℃, if inert gas, the temperature can reach 300 ℃ is still stable. However, the melt is susceptible to degradation when in contact with oxygen.
Application range of LDPE: Suitable for food packaging such as seasoning, pastry, sugar, preserves, biscuits, milk powder, tea, fish and meat pine. Packaging for pharmaceuticals such as tablets and powders, shirts, garments, knitted cotton products and chemical fibre products and other fibre products. Packaging for daily chemical products such as laundry detergent, detergent and cosmetics. Due to the poor mechanical properties of single-layer PE film, it is usually used as the inner layer of composite packaging bags, i.e. multi-layer composite film heat sealing substrate.
