Characteristics of wrapping film
The characteristics of wrapping film are as follows:
unitization: this is one of the greatest characteristics of wrapping film packaging. With the help of the super strong winding force and retraction of the film, the product is tightly and fixedly bundled into a unit, so that the scattered small pieces become a whole, even in an unfavorable environment, the product has no looseness and separation, and has no sharp edges and stickiness to avoid damage.
primary protection: primary protection provides the surface protection of the product and forms a very light and protective appearance around the product, so as to achieve the purpose of dust prevention, oil prevention, moisture prevention, water prevention and theft prevention. It is particularly important that the wrapping film packaging makes the packaged items evenly stressed, avoiding damage to the items caused by uneven stress. This is the traditional packaging method (Bundling, packaging, tape, etc)It cannot be done.
compression fixity: The product is wrapped and packaged by the retraction force of the stretch film to form a compact unit that does not occupy space, the pallets of the products are tightly wrapped together, which can effectively prevent the products from being misplaced and moved during transportation. At the same time, the adjustable tensile force can make the hard products close together, make soft products tight, especially in the tobacco industry and textile industry with unique packaging effect.
cost saving: the use of wrapping film for product packaging can effectively reduce the use cost. The use of wrapping film is only about 15% of the original box packaging and about 35% of the Heat Shrinkable film, about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers and improve the packaging efficiency and packaging grade.
to sum up, the application field of stretch film is very wide, while many fields in China have not been involved, and many fields already involved have not been widely used, with the expansion of application fields, the amount of stretch film will increase greatly, and its market potential is immeasurable. Therefore, it is necessary for us to vigorously promote the production and application of Stretch Films.
Introduction of PE stretch film and stretch film
PE stretch film (Also known as winding film) It has high tensile strength, tear strength and good self-adhesion, so it can wrap the object into a whole and prevent it from collapsing during transportation. The film has excellent transparency. The wrapped object is beautiful and elegant, and can make the object waterproof, dustproof and anti-damage. The film is widely used in cargo pallet packaging, such as electronic, building materials, chemical, metal products, auto parts, wire and cable, daily necessities, food, paper and other industries. Specifications: Machine film width 500, manual film width 300, 350, 450, 500, thickness 15um-50um. Various specifications can be cut online. The viscosity is divided into single-sided adhesive and double-sided adhesive. The product is divided into two series: manual winding film and machine winding film.
Features: The product has good cushioning strength, puncture resistance and tear resistance, thin thickness and good performance-price ratio. It has high tensile strength, tear strength, transparency and good retraction force, 400% pre-stretching ratio, and can be assembled, waterproof, dustproof, scattered and anti-theft. Uses: used in pallet wrapping and other winding packaging, widely used in foreign trade export, bottle making, paper making, hardware and electrical appliances, plastics, chemical industry, building materials, agricultural products, food and other industries.
PE wrapping film is an industrial film product with high tensile strength, high elongation, good self-adhesion, high transparency and so on. It can be used for manual winding film or machine winding film, and can be widely used for centralized packaging of various goods.
PE wrapping film is mainly formed by mixing and extruding several different brands of polyene resin. It has puncture resistance, super strength and high performance, and is wound and packaged for goods stacked on the pallet, it makes the packaging more stable and tidy, more waterproof, and is widely used in foreign trade export, paper making, hardware, plastic chemical, building materials, food and medicine industries.
PE stretch wrapping film: LLDPE stretch wrapping film is based on high-quality LLDPE, with high-quality tackifier, heated, extruded, cast, it is then cooled by a chilling roller, it has the advantages of strong toughness, high elasticity, tear resistance, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, dustproof, waterproof, single-sided adhesion and double-sided adhesion, it can save materials, labor and time when in use, and is widely used in papermaking, logistics, chemical industry, plastic raw materials, building materials, food, glass and other aspects.
PE slitting and winding film: it is made by taking high-quality LLDPE as the base material, adding high-quality tackifier separately, heating, extrusion, tape casting, and cooling by chilling roller, it has the advantages of strong toughness, high elasticity, tear resistance, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, dustproof, waterproof, single-sided adhesion and double-sided adhesion, it can save materials, labor and time when in use, and is widely used in papermaking, logistics, chemical industry, plastic raw materials, building materials, food, glass and other aspects.
The principle of wrapping film
The Wrapping Film bundles the product into a unit in a compact and fixed way with the help of the super strong winding force and retraction of the film, make the scattered small pieces into a whole, even in an unfavorable environment, the product has no looseness and separation, and has no sharp edges and stickiness, so as not to cause damage.
wrapping film can be divided into: PE wrapping film, PE wrapping film, PE stretch wrapping film, LLDPE stretch wrapping film, PE slitting wrapping film, etc.
