At CMB, we produce cold and hot packaging machines. Cold packaging, also known as “bandaged packaging”, is one that uses stretchable polyethylene, which is a material that stretches with cold and shrinks without the need for heat. On the other hand, heat packaging uses shrink polyethylene, which is a film that, when temperature is applied, adapts to the shape of the product.
Their main differences are:
- While both use polyethylene film, one packs by bandaging, while the other does so by shrinking the material through the application of heat.
- Heat packaging lasts longer than cold packaging.
- Cold packaging uses less energy
- Heat packaging supports products with morphologies with greater variations.
- Cold packaging supports the use of bubble film.
Because of these differences is that not all industries can make use of the same machines. This will depend on a series of issues, such as how fragile the product is, its shape and dimensions and how it will be transported, among others.
