As China Plastic Extruder Supplier, China GWELL uses multi-layer co-extrusion technology in PE wrap film extrusion line, which can be more flexible and mature in the use of raw materials according to the needs of different customers, and the formula cost is lower.
GWELL as China Plastic Extruder manufacturer, PE wrap film extrusion line stretch film is developed from a single layer to two layers and three layers. Now the stretch film produced by the casting method is mainly used. The early stretch film is mostly blown film. , This is because the production of the casting line has the advantages of uniform thickness and high transparency, which can be applied to the requirements of high-magnification pre-stretching. The stretch film produced by the China GWELL casting method has high clarity, high elongation, high puncture strength, and tear strength.
PE wrap film extrusion line products have a wide range of applications and are widely used in the integrated packaging of hardware, minerals, chemicals, medicine, food, machinery and other products. Casting film has excellent heat-sealing performance and excellent transparency. It is one of the primary packaging composite substrates for producing high-temperature cooking films, vacuum aluminized films, etc.

In the early stage, LLDPE stretch film was mostly blown film, which developed from single layer to two and three layers; LLDPE stretch film is mainly produced by tape casting because the tape casting line has the advantages of uniform thickness and high transparency, which can be suitable for the requirements of high magnification pre-stretching.
Because single-layer tape casting can‘t do single-sided adhesion, its application field is limited. Single and double-layer casting is not as wide in material selection as three-layer casting, and the formulation cost is also high, so the three-layer coextrusion structure is ideal.
The high-quality tensile film shall have the characteristics of high transparency, high longitudinal elongation, high yield point, high transverse tear strength, and good puncture performance.
As China Plastic Extruder manufacturer, GWELL adopts imported linear polyethylene LLDPE resin and special additives for tackifiers. It can produce multi-functional stretch film such as hand-use, resistance machine, pre-stretching machine, anti-ultraviolet, anti-static, anti-rust and so on.

This kind of packaging means that the film wraps the tray around the tray, and the films at both ends are heat-sealed together through two hot grasps. This form of packaging is relatively early, and now the utilization rate is not high.
The requirement of this packaging form is that the film width is enough to cover the tray, and the width of the film is required, with a thickness of about 17 ~ 35 μ m.
This packaging form is the simplest. A film is installed on the shelf and rotated by the tray or around the tray. This kind of packing is mainly applicable to repackaging after the pallet is wrapped and damaged. The packaging speed is relatively slow, and the thickness of the film is required to be 15 ~ 20 μ m.
This packaging form belongs to mechanical packaging, which is mainly rotated by the tray or the film around the tray. The film is fixed on the support and can move up and down. The packaging capacity is very strong, about 15 ~ 18 plates per hour.
This kind of packaging means that the film should rotate around the goods, which is more suitable for long goods packaging, such as carpet, plate, fiberboard, special-shaped materials, etc. it is also common in life.
This is also the latest packaging form. The advantages of this packaging are obvious. It can reduce the consumption of materials and reduce the storage space of pallets. It is especially popular abroad.
This kind of packaging requires the packaging equipment to be installed at the end of the production line and fully automatically stretch the film, so that it can replace the tape to bind the materials and play a good protective role.
