Application of pvc heat shrinkable film in daily life

PVC shrink film is a kind of thermoplastic film that is stretched and oriented during the production process and shrinks by heat during use. The heat shrinkage of the film has been applied as early as 1936. At first, rubber film was mainly used to shrink packaging perishable food. Nowadays, heat shrink technology has been developed to almost use plastic shrink film to package various commodities. In addition, shrink packaging is also used to make shrink labels and shrink bottle caps, so that containers that are not easy to print or have complex shapes can be labeled. Recently, newer application areas have been developed continuously. Production technology and characteristics The production of packaging film usually adopts extrusion blow molding or extrusion casting method to produce thick film, and then longitudinal and transverse stretch at a high elastic temperature above the softening temperature and below the melting temperature, or only Stretching is oriented in one direction and not stretching in the other direction. The former is called biaxially stretched shrink film, and the latter is called unidirectional shrink film. When in use, when the temperature is higher than the stretching temperature or close to the stretching temperature, the packaged goods can be wrapped with reliable contraction force. PVC heat shrinkable film is mainly used for food and beverages. Based on the non-toxic and non-polluting PVC shrink film, it is used for outer packaging. It has elegant appearance, smooth, transparent, strong toughness, good sealing, and is used for quality, freshness, dustproof, It has excellent functions for preventing moisture, damage and pollution, and is deeply loved by manufacturers. Pvc heat shrinkable film is not only used in foods, but also used in cosmetics. PVC shrinkable film is very ideal for high-end cosmetics packaging. Therefore, pvc shrinkable film has an indispensable position in our daily life. PVC heat shrinkable film is used as the packaging of many products because of its easy deformation, such as the packaging of common stationery in our lives, the outer packaging of beverage bottles, and the packaging of some tableware are made of PVC heat shrinkable film. They generally have Strong elastic tension, can wrap the goods well, can effectively prevent the goods from being damaged, and avoid the looseness and deformation of the goods due to the lack of packaging. This advantage makes the PVC heat shrinkable film according to the customer's Different needs make different deformations. Meet their different needs. Strong oxidation resistance. Many industries are now applying it, such as the packaging of sterilized tableware in the catering industry, the anti-oxidation inner packaging of handicrafts, and the inner bag of toys. They play a great role in various fields. This is a kind of magic. effect. With the development of the shrink film market, the homogeneity of shrink film products has become more and more obvious, and the shrink film produced by various shrink film manufacturers is getting smaller and smaller. Therefore, increasing efforts in shrink film packaging can highlight the product theme and attract consumers. In the subdivided shrink film market, the design of PVC shrink film that meets the needs of different similar shrink film markets also reflects the skill of a manufacturer in market promotion. With environmental protection as the background of the industry, more and more manufacturers choose low-carbon and environmentally friendly packaging methods and packaging materials by increasing Ru0026D technologies. Well-known manufacturers in the industry have put forward the slogan of packaging environmental protection, using new technologies and new materials, introducing cleaner production mechanisms, and (economic model) production methods and product structures based on green, environmentally friendly low energy consumption, low pollution, and low emissions, thereby reducing Carbon emissions and sustainable economic development. With the widespread use of PVC shrink film in daily life, manufacturers should meet the requirements of simplicity, practicality, and environmental protection from the beginning of packaging design. One of the biggest characteristics of PVC shrink film packaging. With the strong winding force and retraction of the film, the product is compactly and fixedly bundled into a unit, so that the scattered small pieces become a whole, even in unfavorable environments, the product has no looseness or separation, and no sharpness. The edges and stickiness to avoid damage. Previous: The essence of PVC is a kind of vacuum blister film. Next: It started with weapons and then used for food packaging!
