What you should know about PE shrink film

If you are looking for quality PE shrink film, you are in the right place. We have a wide selection of shrink films available.

The polyethylene shrink film market is primarily driven by growth in the food and beverage, pharmaceutical, and packaging industries. Growing demand for packaged products is expected to create lucrative opportunities for market players. Nonetheless, the global market for polyethylene shrink films, which are mainly used for canned products and packaged foods, is hampered by several factors.

The membrane is waterproof and very durable. Its high puncture and tear resistance makes it an excellent choice for wrapping large or heavy items. Also, PE shrink film is an excellent choice for printing as it provides UV protection for up to 9 months.

Low-density polyethylene

The production process of LDPE PE shrink film can vary greatly depending on the factory's recipe, raw materials, machines and team expertise. It consists of several steps including formulating plastic resin, blowing the film and winding it into a core. In some factories, the process is automated, while others require controllers at every step.

High-density polyethylene

Shrink film is used to store and transport almost all types of products. This type of material comes in many different forms and has many benefits. It allows you to pack more items per delivery, helping to close product-to-product gaps, reduce shipping costs, and increase sales. However, there are a few things you should consider before purchasing shrink film for your packaging needs.

First of all, you should know that there are two types of shrink film: MD and TD. Each of these types has a different melt index and has different properties. The process parameters that determine dimensional characteristics and shrinkage values ​​vary by application type. LDPE is a common shrink film material, but some MFI low density polyethylenes are also a viable option. In addition, other materials can be added to impart special properties to the film.

direction

Orientation refers to the orientation of the polymer molecules. The term is often used interchangeably with heat shrinkage and refers to the ability of a material to return to its original dimensions when heated. Hot blown materials have low shrinkage tension and return to their original dimensions once the temperature is raised.

PE shrink films are usually produced as multi-layer materials. The film is made by co-extruding polymers, each with a different orientation. Polyolefin shrink films are typically biaxially oriented.

melting point

PE shrink film is composed of two major types of plastics: polyvinyl chloride and polyolefin. Both materials have low modulus and low crystallinity. Polymers based on these materials exhibit improved shrinkage onset and modulus reduction. Polyolefin polymers are superior to polypropylene.

Polyolefin shrink films are commonly used in the manufacture of toys, sporting goods, hardware, household items and greeting cards. It is also commonly used in industrial parts. Its melting point is about 190°C.

cost

If you are planning to buy PE shrink film, you should know a few things. An important thing to know is the length of the roll. While the length of the film does not affect its price, it is an important factor to consider when purchasing film. The length of the bag is called the cut-off and should be chosen carefully to minimize waste and maximize the use of each roll.

PE shrink film is one of the best choices for packaging due to its high quality and low cost. It's made from recyclable materials, which makes it an eco-friendly option. It also comes in different types and the price depends on the type you need.
