How to choose the material of the shrink label
For shrink labels or shrink sleeves, there are OPS/PE/PVC/POF/PET materials. Different materials, different specialties.
1) PE heat shrinkable film is widely used in complete packaging of wine, cans, mineral water, various beverages, cloth products, etc. This product has good flexibility, impact resistance, strong tear resistance, is not easy to break, is afraid of moisture, and shrinks big.
2) PVC film has high transparency, good gloss and high shrinkage.
3) POF has the characteristics of high surface gloss, good toughness, high tear resistance, uniform heat shrinkage and is suitable for automatic high-speed packaging. It is an updated product of traditional PVC heat shrinkable film.
POF means heat-shrinkable film. The full name of POF is multi-layer co-extruded polyethylene heat-shrinkable film. It uses linear low-density polyethylene as the middle layer (LLDPE), polypropylene (pp) as the inner and outer layers, and is extruded through three layers of plasticization. Extruded, and then processed by special processes such as die forming, film blowing and foam blowing.
4) OPS heat shrinkable film (oriented polystyrene) heat shrinkable film is a new type of post-OPS heat shrinkable film packaging material that meets environmental protection requirements. OPS heat shrinkable film has the characteristics of high strength, high rigidity, stable shape, and good scalability. . transparency.
It is easy to process, easy to color, good printing performance, and has extremely high printing resolution. It is a material progress for trademarks that are constantly pursuing exquisite printing.
Due to the high shrinkage and strength of the OPS film, it can be tightly attached to containers of different shapes, so it can not only print exquisite patterns, but also meet the use of new packaging containers of various shapes, non-toxic, tasteless, and oil-resistant , The film that meets food hygiene standards allows designers to use eye-catching colors to achieve 360° label design, give full play to their creativity and imagination, and make the patterns used on labels of beverages and other commodities more vivid, and the image highlights on the shelves , producing unexpected container effects.
