Shrink film, which shrinks when it comes into contact with heat, is a preferred packaging material in many sectors. It allows products to be wrapped easily and eliminates problems such as shaking, tipping or deterioration. Shrink film types provide great comfort in the transportation of multiple products. You need to minimize the difficulties experienced in the use of films produced from LDPE raw material.

What to Consider When Choosing Shrink Film?

Shrink film has printed and unprinted, perforated and non-perforated varieties. Points to consider to choosing the right product are:

• Finding the suitable variety for your intended use ensures that the products you wrap are stored safely. LDPE shrink film types are resistant to external factors such as heat, humidity and impact and they are frequently preferred in large product groups.
• Details such as thickness, length and quantity of shrink films play an important role in your choices.
• This product is preferred in sectors such as food, beverage and pharmaceuticals and it eliminates situations such as deterioration.
• Devices such as heat guns or shrink machines ensure the quality of the packaging stage.

What are Shrink Film Packaging Errors and Solutions?

Shrink film is used as a result of the correct adjustment and regular maintenance of the machine. The packaging errors experienced as a result of any malfunction are as follows:

• The lobes formed at the corners of the packages can be corrected by increasing the temperature ratio of the heat tunnel and the fan setting.
• Crystallization of the film due to excessive heat can be solved by reducing the conveyor speed of the heat tunnel or increasing the number of punching needles.
• Wrinkles occur because the shrink film rides up in the corners of the packages. This is corrected by using the right size product and increasing the heat tunnel temperature.
• A fisheye appearance occurs on the packaging. A smooth appearance can be created by using the most suitable film for the product and machine or by increasing the heat tunnel temperature.
• Round or oval holes may appear on the packaging. You can solve this problem by checking the perforation roll and lowering the heat tunnel temperature.
• The side welds can be opened or weak. You can check the wire for even heat application, remove film residue or inspect the weld bed for foreign material.
• Slippage in the welding position adversely affects the appearance of the products. The width and length ratio of the film must be balanced and the conveyor belt height must be aligned to the center of the product.
