The uses and advantages of the shrink bag

What is a shrink bag ?

A shrink bag works like a regular vacuum pouch, we must first extract all the air from the bag before sealing it.

We then dip the entire packaging in warm water to shrink it onto the product while also reducing excess plastic. The ideal water temperature for shrinking the bags is 190°F to195°F or (89°C to 91°C). Dip for two seconds maximum.

Its advantages

Makes an attractive packaging which molds the product, primarily used on products with irregular shapes like ham, poultry etc.

Even slightly punctured, the bag continues to mold and protect the product. By reducing contact with air, we stop oxidation and the growth of bacteria or mold.

Reduces loss of humidity and eliminates freezer burn completely. Certain models protect against Ultraviolet Rays which are often responsible for the change in pigmentation of food products. By conserving all of the product humidity, we maintain its full weight, as well as its full monetary value.

It is important that the product be rotated and that each box be easily identified. Do not use knives or other cutting instruments to open the boxes, to prevent any damage to the bags.

Your packaging is your most important promotional tool.

Yes we print ! It is possible to print a shrink bag, however we must take in account the fact that our bags can shrink up to 40% in certain cases, which will distort the printed images. Several colours are available in addition to clear bags: WHITE - RED - GOLD - BURNT ORANGE or LIGHLY TINTED
Our computer graphic department can advise you on how to proceed.
