Large three-dimensional aluminum foil bags - plastic film vacuum bags plastic composite film composite membrane types of plastic into plastic film and aluminum composite membrane two kinds. Plastic film structures 1, PET / aluminum CPP (lightweight product structure) 2, PET / AL / PE (10KG below with structure) 3, PET / AL / CPP (use of pesticides structure) 4, PET / AL / NY / PE (re-use of packaging structure) product thickness can recommend or light products according to customer requirements thickness recommend sided 4-sided silk pesticide products recommend a thickness of 10 silk repackaged product recommendations based on product features single wire thickness of 12 to 15 wire Product specification roll film width: 1000mm ~ 1500mm. 1000 m length is generally triangular envelope bags: width 50mm ~ 1000mm length 2.5 Mira chain bag: Width 50mm ~ 1200mm height: 1 meter Features flexibility, moisture and oxygen barrier, shading, shielding, antistatic, can be evacuated, You can color printing. Each used a different material structure, leading to the final performance is not the same. Indicators 10 times or even a hundred times may vary. Scope can be used for food, medicine, pesticide, chemical, mechanical and electrical products. Paper packaging for all of us are familiar with, it gives us a very environmentally friendly feeling. However, some manufacturers in pursuit of food packaging visual sense, also led to the emergence of multi-degree packaging. The role of paper in the paper-plastic composite materials primarily to give people a sense of paper and packaging materials to improve the stiffness of the visual, the barrier packaging material and peel / heat seal strength no real contribution, but sometimes a disadvantage a.
