Basic Information
PE stretch film, full name polyethylene stretch wrap film, is made from high-quality linear low-density polyethylene (LLDPE) as the base material, combined with premium tackifiers and metallocene catalysts, processed through heating, extrusion, casting, and then rapidly cooled.
Features
Good self-adhesion: Can tightly adhere to the surface of objects after stretching without the need for additional adhesives or tying, securely wrapping items to prevent them from coming apart during transportation or storage.
High transparency: Has good clarity, making the packaged items clearly visible, facilitating the inspection of the item's condition and quantity, and enhancing the appearance of the packaging.
Good protective performance: Effectively blocks moisture and dust intrusion, protecting the packaged items from external environmental impacts. It also has good puncture resistance and tear resistance, preventing damage from sharp objects during handling.
Environmentally safe: Made from environmentally friendly and recyclable materials, odorless and non-toxic, suitable for direct packaging of items, complying with national environmental standards.
Production process: Mainly uses the casting method, involving heating the raw materials, extrusion, casting, and rapid cooling. The flow channel is long and narrow with a fast flow rate. The melt temperature is generally controlled between 180°C and 220°C, casting cooling temperature is controlled between 20°C and 30°C, and the winding tension is kept low, generally within 10kg, to facilitate the migration of tackifiers and reduce internal stress in the finished film.
Application fields
Logistics and transportation: Widely used for pallet cargo wrapping, it can secure goods into a single unit, preventing collapse or scattering during transportation and protecting goods from damage.
Industrial product packaging: Suitable for packaging various industrial products such as electronic components, mechanical parts, building materials, and chemical products, effectively preventing dust, moisture, and scratches.
Agricultural field: In fruit tree cultivation, it can be used as stump film to retain moisture and warmth, aiding wound healing and improving tree survival rates; in vegetable planting, PE stretch grafting film can be used to fix grafting sites on seedlings, promoting wound healing and plant growth.
Daily life: Can be used to wrap books, clothes, food, and other miscellaneous items, making storage and organization convenient.
