A great way to keep your product safe and ready for sale is with shrink film. It creates a tight, tamper-resistant seal and can protect it from damage during transit or in storage. It also adds to the aesthetic appeal of your packaging. However, there are many kinds of shrink films on the market today, so it’s important to know which one is right for your needs.
The most common type of shrink wrap is low-density polyethylene (LDPE) film. This is a versatile and inexpensive material that can be used for a wide range of applications. It’s often combined with other materials to provide specific properties, such as UV protection or clarity. LDPE can also be made thicker than other types of films to increase durability and strength.
Polyolefin shrink film is another popular option. It’s available in a variety of colors, thicknesses and finishes to meet your packaging requirements. It’s commonly used for beverage multipacks, but it can also be used for other products, such as sports goods, electronics and food items. It can be printed or laminated to add additional value to your package.
Shrink films can be produced with a variety of different techniques, but the most common is through co-extrusion. This process involves feeding several extruders with different types of plastic resins and combining them to create a single, multi-layered film. It’s an efficient and cost-effective method of producing high-quality PE films.
Another benefit of PE shrink film is its resistance to abrasions and chemicals. This makes it an excellent choice for shipping and storing bulky or oversized items. It is also able to withstand temperature changes, which means it can be used in a variety of climates.
PE heat shrink film can help reduce packaging costs by providing a sanitary, convenient and environmentally friendly way to bundle products. It also has the added advantage of saving space compared to traditional corrugated cardboard boxes, which can become damaged during transit. It’s also durable and strong, and can be used for many applications, including logistics, food packaging, furniture and stationery, white goods, water bottles and hand tools.
A good blown film extrusion line is key for producing quality PE shrink film. Choosing the right model will help you achieve optimal production efficiency, product quality and performance. The best lines for PE shrink film use a three-layer co-extrusion process to produce high-quality, customized polyolefin films.
There are also a number of other factors to consider when selecting a blown film extrusion line. These include the desired properties of your film, its intended application and the size of your facility.
There are also a variety of ways to save money when purchasing PE shrink film, including buying in bulk and cutting down on packaging size. Depending on your product, you can usually save up to 9.1% on your material costs by using a smaller film than the recommended size for your machine. To find out how much you can save, simply pack a sample of your product with the suggested film size and then measure it from one end seal to the other. Then, divide the difference by the number of packages per roll to see how much you can save.
