Big Bags with Inner liner, more protection

Big Bags with inner bag

Big Bags with Polyethylene (PE) inner sleeve allow products to be packaged avoiding direct contact with the Polypropylene that is part of the fabric of Big Bag. In this way, the contents remain more and better insulated from the outside, also reducing its transpiration.

In the case of very dusty products, this inner sleeve also prevents leakage through the walls, base or seams of Big Bag.

It is very important to supply this type of Big Bags with the inner sleeve properly placed inside so that, during the filling process, the inner sleeve does not fold in an undesired way and so that during transportation the sleeve does not break. Thus, the sleeves can be simply placed inside the Big Bag, glued to the walls, attached by side ties and/or sewn to the top of the mouth of the Big Bag.

Different types of inner liners

The inner liners can have basic configurations in the shape of a cube like the body of the Big Bag, or include cylindrical extensions at the top and/or bottom so that they also cover the loading and unloading valves internally.

In some cases, the inner sleeves should be blue or black, among others, in order to better locate possible remains of the contained product, such as pine nuts, for example.

The inner sleeves can be supplied in High Density Polyethylene (HDPE) or Low Density Polyethylene (LDPE), or even in other materials such as aluminum (all with different thicknesses, strengths and insulation grades).
