People often face the problem of lack of time. Semi-finished products, including dumplings, are in high demand among the population, as they are quickly and simply cooked. To prepare them, you need a minimum of time and culinary knowledge. But in order for the frozen products from the manufacturer to arrive diligently to the consumer, it is important to pack them in special packaging. Not all packaging is suitable for convenience foods.
What is the package for dumplings?
For reliable protection against external factors must possess such qualities:
- resistance to frost during deep freezing;
- good heat sealability;
- flexibility and resistance to punctures;
- lack of fragility when freezing.
In this regard, for packaging dumplings and other semi-finished products, a film of polyethylene and polypropylene is used.
Surface Printed Multilayer PE Films
Multiple-layer polyethylene films are often used for packaging frozen foods. They have good operational capabilities, but at the same time their price is low. The pattern on such packaging is printed on the surface of the film. The film is white or transparent with a pronounced shine.
PE / PE with interlayer printing
This is a combination of two plastic films between which there is a seal. Such packaging has a high resistance to punctures, welding seams at low temperatures do not lose their integrity. This ensures packaging integrity as well as product retention. In addition, the pattern spread between the layers of the film does not wear out.
Transparent PET / PE white or transparent with interlayer printing
A composition of these materials is most often used for packaging dumplings and other frozen products. Such packaging has excellent frost resistance, strength and puncture resistance. Good barrier properties keep products well from external factors, including moisture and odors. In addition, the film has an attractive appearance. A composition of such materials is excellent for filling equipment operating at high speeds.
BOPP transparent / PE white or transparent with interlayer printing
The use of transparent BOPP in the composition improves the aesthetic appearance of the package. Thanks to this material, the packaging acquires an attractive shine and gloss. But most importantly, the BOPP film differs from PE in its best properties to withstand subzero temperatures, strength and puncture resistance. Welding seams perfectly retain their integrity. Also, the material is perfect for use on filling equipment.
