Shrink Films Good Shrinkage And A Certain Shrinkage Stress

Oct 31, 2017

Shrink film has high puncture resistance, good shrinkage and a certain shrinkage stress. Mainly used for a variety of products sales and transportation process, used to secure, cover and protect the product. Shrink packaging is not only beautiful appearance, but also play a moisture, dust, anti-loose, anti-theft, the role of the collection.

Shrink film is used for the sale and transportation of various products. Its main role is to secure, cover and protect the product. Shrink film must have high puncture resistance, good shrinkage and a certain shrinkage stress. In the process of shrinkage, the film can not produce holes. As the shrink film is often applied to the outside, so need to add UV anti-ultraviolet agent.

1) PE heat shrinkable film is widely used in alcohol, cans, mineral water, all kinds of beverages, cloth and other products of the whole set of packaging, the product flexibility, impact resistance, tear resistance, easy to break , Not afraid of tide, shrinkage;

2) PVC film with high transparency, good gloss, high shrinkage characteristics;

3) POF surface high gloss, good toughness, tear strength, heat shrinkage uniform and suitable for high-speed automatic packaging and other characteristics, is the traditional PVC shrinking film replacement products. POF is the meaning of shrinking film, POF full name multi-layer co-extruded polyolefin heat shrinkable film, it is the linear low-density polyethylene as the intermediate layer (LLDPE), polypropylene (pp) as the inner and outer, Out of plastic extrusion, and then by the die forming, film bubble inflation and other special processing from the process.

4) OPS shrink film (oriented polystyrene) heat shrinkable film is a kind of environmentally friendly requirements of the new paste ops heat shrinkable film packaging materials, OPS heat shrinkable film with high strength, rigidity, shape and stability, and has a good luster Degree and transparency. Easy processing, easy to color, printing performance, and a very high printing resolution, for the constant pursuit of fine printing of the trademark, is a material improvement. Due to the high shrinkage and strength of the OPS film, it can be tightly fitted with a variety of containers of different shapes, so it not only prints exquisite designs, but also satisfies the use of novel packaging containers with a wide variety of shapes. A non-toxic and tasteless, grease-resistant, hygienic film allows designers to use a compelling color to achieve 360 ° label design, giving full play to creativity and imagination, so that beverages and other goods on the label The use of patterns more vivid, highlighting the image on the shelves, resulting in an unexpected container effect.

5) PET heat shrinkable polyester film characteristics: it is stable at room temperature, heating (above the glass transition temperature) contraction, and is more than 70% in one direction of heat shrinkage. Heat shrinkable polyester film packaging advantages are: ① body transparent, reflecting the image of goods. ② tight packing, good dispersion. ③ rain, moisture, mildew. ④ no recovery, there is a certain anti-counterfeiting function. Heat shrinkable polyester film is often used in convenience food, beverage market, electronic appliances, metal products, especially shrink labels is its most important application areas. Because with the rapid development of PET beverage bottles, such as Coke, Sprite, a variety of fruit juice bottles and other beverage bottles are required PET heat shrink film with supporting heat sealing labels, they belong to the same polyester, environmentally friendly materials, easy recycling use.

Heat shrinkable polyester film in addition to used as a shrink label, and now also began to use for daily merchandise packaging. Because it can protect the packaging items to avoid the impact, rain, moisture, rust, but also make the product to print the exquisite packaging to win the user, while it can be a good display of the manufacturer's good image. Today, more and more packaging manufacturers use printed shrink film instead of the traditional transparent film. Because the printing shrink film can improve the appearance of the product grade, is conducive to product advertising, trademark brands in the minds of consumers can have a deep impression.
