Environmentally-friendly multi-layer co-extruded polyolefin (PO) heat-shrinkable films use linear low-density polyethylene (LLDPE) as the intermediate layer and polypropylene (PP) as the inner and outer layers in special equipment. The inner and outer three layers are co-extruded to form a heat-shrinkable film with high transparency, high shrinkage, and good heat-sealability. It also has all the advantages and advantages of polyethylene (PE) and polypropylene (PP), and its excellent performance is far superior to pure polyethylene (PE) and polypropylene (PP) membranes. It is currently internationally Widely promote the use of environmentally friendly heat-shrinkable packaging materials approved by European and American markets.
It complies with the US FDA and USDA standards. It is made of environmentally friendly materials and is an environmentally friendly packaging material that can be recycled and reused. Particularly suitable for the pharmaceutical industry, food industry. The product meets "GMP" requirements.
It has the following features:
1. High shrinkage rate 2. Glossiness High transparency 3. Good toughness, not easy to age 4. Low density, can reduce packaging cost 5. Good welding performance, not easy to open 6. High tear strength 7. Soft at low temperatures, not easily broken 8. Wide application range Can use automatic, semi-automatic mechanical operation or manual operation of packaging, but also according to the different packaging methods of the use of more reasonable packaging machinery. At present, this product has been widely used in many industries, such as daily necessities, food hygiene products, pharmaceuticals, cultural and educational supplies, cosmetics, audio-visual products, native products, kitchen supplies, clothing supplies, clothing textiles, toys, handicrafts, beverages , fruits, vegetables, frozen foods, etc.
PO and PP, PVC shrink film physical properties compared pros and cons PO (environmental) shrink film PP shrink film PVC shrink film First, the cost ratio of 0.92, the thickness of the thinnest 0.012mm, the actual unit cost is lower.
The specific gravity is 0.90, the thickness is the smallest 0.012-0.015mm, and the actual unit cost is low.
The proportion of 1.4, the thinnest thickness of 0.018-0.02mm, the actual unit cost is higher.
Second, thin and tough properties, uniform thickness, good moisture resistance, soft texture. High tensile strength, high tear strength, adjustable shrinkage. Due to the presence of LLDPE, rub resistance is better.
Thin and tough, uniform thickness, good moisture resistance, soft texture. Tear strength is lower than PO, but much higher than PVC, poor adjustability of shrinkage. Resistance to rubbing is not as good as PO.
Thin and tough, uneven thickness, poor moisture resistance, texture hard and brittle. Low strength, low shrinkage. Resistance to rubbing is poor.
Third, commodity prices are extremely cold-resistant, -50 °C is not hard not brittle, not easily broken, can be used for frozen food packaging. After shrink packaging, -50°C-95°C is stored for a long period of time and is stable. With static electricity and anti-fog treatment, it is not easy to contaminate dust and keep the product clean and beautiful.
Cold resistance is excellent in winter or after freezing, it is not hard and embrittlement, so the transportation is not easy to break. Elimination of static electricity eliminates dust and keeps the product clean.
Cold resistance is extremely poor, and embrittlement occurs in winter or after freezing, and therefore it is easily broken during transportation. The longer the shrink packs, the tighter the shrinkage will be and the deformation of the packaged product. No static elimination treatment, easily contaminated with dust, blurred product contamination.
Fourth, the processing performance of the process does not produce water will not stick to the sealing rod, maintenance and operation is easy. High toughness, smoothness and resistance to rubbing, making it suitable for automatic packaging of high-speed production lines. The process does not generate moisture, nor stick on the sealing rod, and maintenance and operation are easy. High toughness, low kneading, can be used for automatic packaging of high-speed production lines.
The process will produce water, which can easily cause mechanical damage, and it is easy to stick on the sealing rod. It is inconvenient to work and difficult to maintain.
Fifth, after the safety shrinks the packing, the four corners of the seal are soft and will not cut people's hands or rub.
After shrinking the packaging, the corners of the seal are soft and will not cut people's hands. After shrinking the package, the corners of the seal are hard and sharp, making it easy to cut blood.
6. Environmental protection and hygiene are non-toxic and no toxic odor is produced during processing. It complies with the FDA and USDA standards. Non-toxic,No toxic gases are produce in geat-seal procell,It accord with American standard of FDA&USDA
It is non-toxic and does not produce toxic odors during processing. It complies with FDA and USDA standards. Non-toxic, No toxic gases are produced in geat-seal procell, It accord with toxic, processing will produce odor, toxic gases, gradually disabled. Toxic during the heatsealing Odor and noxiousgases will be produced,forbiden to use in near future (This article is provided by Shanghai Shengyu Packaging Machinery Co., Ltd.)
