What is Polyolefin?
(Poly-ole-fin) is a polymer compound consisting of carbon and hydrogen; the root word olefin refers to any member of the olefin family. An olefin is an unsaturated compound that contains at least one double carbon bond. Ethylenes are one of the most common olefins. They are composed of the monomers ethylene (C2H4) and propylene (C3H6). Polyolefins include polyethylene (PE), polypropylene (PP), and polybutylene (PB). They are characterized by low density, good corrosion resistance, high malleability, and exceptional heat resistance. Polyolefins are used in a variety of industries, including food packaging, automotive, cosmetics, adhesives, packaging, etc. Polyolefin shrink film is the most common form of polyolefin used in the packaging industry.
Polyolefin shrink packaging offers many advantages over PVC shrink packaging. In recent years, polyolefins have become the shrink material of choice for most shrink packaging applications. Our polyolefin shrink films are FDA approved for direct food contact.
More details on POF can be found on Wikipedia.
Are POF shrink wrap and POF shrink film the same thing?
Yes, POF shrink wrap and POF shrink film are essentially the same thing. They both refer to a type of heat-shrinkable film made from polyolefin (POF) that is used for packaging various products such as food, cosmetics, stationery, and more.
The density of POF shrink film
POF shrink film has a density range of 0.91 to 0.93 g/cm³, which makes it relatively lightweight compared to other types of plastic film. Its low density allows it to be easily stretched and shaped around objects, making it ideal for wrapping irregularly shaped products. The thickness of the film can affect its density and high performance film have characteristics, such as its ability to withstand tearing or puncturing. Despite variations in density, POF shrink film is commonly used in industries such as food and beverage, cosmetics, and pharmaceuticals due to its excellent clarity, seal strength, and resistance to moisture and punctures.
pof shrink film material
The raw material used for POF shrink film is polyolefin, which is an important type of thermoplastic plastic material primarily composed of olefin monomers. This material has several advantages over polyethylene (PE), making POF (polyolefin) highly suitable for use as shrink film. It features high transparency and the ability to tightly wrap objects, providing excellent protection and display effects.
What are the types of colored POF shrink films?
Colored POF shrink films are available in various colors such as red, blue, green, yellow, and more. They are classified based on individual colors. However, POF shrink films can also be categorized into translucent shrink films, transparent shrink films, and gradient-colored POF shrink films. The gradient-colored films exhibit a gradual transition of colors. Transparent POF shrink films are typically colorless.
What industries can Polyolefin be used in?
Polyolefin is an important polymer material that can be used in the following industries:
Packaging industry: Polyolefin can be used in packaging materials for food, medicine, and daily necessities, such as plastic film, cling film, foam box, fruit packaging film, noodle film, egg packaging film, etc.
Textile industry: polyolefin can be used in textile manufacturing, such as washcloths, slippers, cloth shoes, etc.
Construction industry: polyolefin can be used for impermeable, waterproof, heat insulation and other construction materials, such as waterproof membranes, insulation materials, etc.
Medical industry: polyolefin can be used in the manufacture of medical dressings, infusion bags, medical equipment, etc.
Automobile industry: polyolefin can be used to manufacture hoods, front windshields, doors, and other structural parts, and can also be used for automobile interior parts.
Electronic industry: polyolefin can be used in the manufacture of battery shells, conductive plastics, cable sheaths, and other materials.
What is biodegradable POF shrink film?
"Biodegradable POF shrink film" is a biodegradable POF shrink film. It is made of materials such as polypropylene (PP) and polylactic acid (PLA), which can be decomposed into the natural environment to reduce environmental pollution. It has the same advantages as traditional POF shrink film, such as high transparency, high shrinkage, and tear resistance.
Biodegradable POF shrink film is a sustainable alternative to traditional POF shrink film, providing the same benefits while reducing the environmental impact. Companies like ZhongDa are leading the way in developing and producing this type of film, helping to promote more eco-friendly packaging practices.
