Paper-plastic packaging full disclosure

Paper-plastic packaging is also a kind of composite film packaging, generally by paper print ( Kraft paper, coated paper, etc. ) Two or three layer of plastic film and composite. Concrete is divided into common aluminum composite paper-plastic and paper-plastic composite membranes. With the improvement of living standard, people's environmental awareness has been strengthened. Kraft paper with simple appearance give a person a kind of warmth nostalgic feeling, its natural brown to packaging adds a lasting appeal, favored by consumers. After a few years ago of excessive packaging and regulation, as the environmental protection consciousness, cutting-edge fashion, the style of packaging is changing quietly, by the leading brand of guidance, paper-plastic packaging is becoming a great focus in the industry. Paper-plastic packaging film paper-plastic packaging materials structure is using laminating adhesive film with printed material composite. Zhisu composite involved in the surface of the species is very complex, in terms of its composite materials, plastic layer biaxial stretching polypropylene ( BOPP) , polyethylene ( PE) , nylon ( 纽约经度) , polyester ( PET) , PVC ( PVC) And so on; Paper layer is pure paper, coated paper ( Bond paper and paper) ; Ink layer and can be divided into water-based ink and oily ink layer. Paper-plastic packaging application of paper-plastic composite film is generally applied to a variety of foods such as candy, biscuit, melon seeds, paper-plastic packaging aluminum is widely used in liquid dairy products, vegetable protein drinks, juice drinks, alcohol and drinking water, such as processing, aseptic packaging materials to packaging including milk, fruit juice and beverage, wine, water, tomato products, soup, sweet food, nutrition, food and other products. The advantages of paper-plastic packaging paper-plastic packaging printing surface bright color ( Rich stereo feeling) Smooth, shiny, anti-fouling, corrosion resistant color loss, improve the tear strength, crushing and preservation function to a certain extent. And paper-plastic products has a large load, not easy to damage, long service life, acid and alkali resistance, ageing resistance, absorption temperature, mould cavity, not easy to deformation, etc, therefore is widely applied to book covers, wine box, shoe, clothing box, gift boxes production, toys and other products. 3. Paper-plastic packaging processing/production process at present paper-plastic composite process are mainly dry compound and water-based cold compound. Dry compound type is the emulsion acrylate adhesive coating on the plastic film, drying moisture, under the effect of hot pressing roller are sticky flow respectively, so as to achieve the aim of the bonding of the composite surface, the method has a strong adaptability to complex, high bonding strength and production of high efficiency, low cost advantages, become the mainstream of composite technology. Water-based glue film is water-based adhesive emulsion coating on the polymer membranes, with the paper directly to smaller pressure joint, adopting natural curing process.
