Feature of PET stretch film

China Plastic Extruder manufacturer – GWELL According to the requirements of the application field for the special properties of the film, the film not only has the excellent physical and mechanical properties of polyester film, but also has excellent optical properties, good transparency, low haze, high gloss, heat Good stability, low thermal shrinkage, smooth surface, good peelability, light aging resistance, etc., and OPET thin mold also has the characteristics of high unidirectional tensile strength and unidirectional orientation, which is suitable for special fields. Polyester film shrink film is a new type of packaging material, which is easy to recycle, tasteless, and has good mechanical properties, especially in line with environmental protection requirements.

Features of China PET Stretch Film Extrusion Line Equipment

The preheating roll, stretching roll, annealing roll and cooling roll of China GWELL PET Stretch Film Extrusion Line are all driven by servo motors, and the speed control precision is higher.
The spacing of the stretching rollers is adjustable, which can achieve “zero spacing” stretching and reduce the necking effect.
Single-point and double-point stretching are optional, and the stretching ratio is continuously adjustable.
Applicable to PET/PP/PE/PA and other materials, the stretching ratio is in the range of 1-10 times, various stretching forms, multi-point stretching structure, and the line speed can reach 200m/min.
Oil/electric heating optional: oil heating temperature is uniform, while electric heating can obtain higher process temperature.
The side plate is provided with a labyrinth film guiding groove, which is convenient for manual film guiding.
Aluminum alloy integral side plate frame, light weight, high strength, corrosion resistance and long service life.
GWELL as a plastic extruder manufacturer high-performance PLC with 12-inch touch screen, high control precision and easy operation. The two-point stretching process can greatly improve film properties, such as film barrier properties, stiffness, flatness, tensile strength, and porosity.

Feature of PET stretch film extrusion line

Single screw or twin-screw extruder structure can be used to produce cast films with single-layer, double-layer, or three-layer co-extrusion structure.
China Plastic Extruder Supplier – GWELL adopts a specially designed extrusion process according to the particularity of PET materials or the characteristics of modified PET materials, after dehumidification and drying-automatic metering and feeding-extruder plasticization-T-type casting die-processing produce high-quality products.
