The multi-layer co-extruded thermoforming film produced by Xianghe is made by co-extrusion casting water cooling process or annular down-blowing water cooling process, and has excellent hot stretching formability, transparency, appearance display effect and good mechanical properties. Xianghe can provide EVOH high barrier or PA medium barrier meat packaging materials with aroma preservation, taste preservation and UV protection according to customer requirements.
xhpak can easily adjust the stretching depth, stiffness and packaging capacity by adjusting the thickness and formula of the film, and adapt to the needs of high-speed packaging by designing the heat sealing performance of the heat sealing layer. Xianghe can design co-extrusion molding with easy-to-open, easy-to-tear and easy-to-peel effects according to needs.
Thermoforming packaging process flow:
① Film roll ② Preheating ③ Thermoforming ④ Loading space ⑤ Coding ⑥ Covering film ⑦ Heat sealing ⑧ Trimming
② XH Forming main specifications
