Bag-in-box packaging is commonly made of two basic structures: metallized and transparent. Sometimes, if no barrier properties needed, both internal and external layers of bag-in-box can be produced with PE film. In this article, we are going to examine the key pros and cons of met PET and EVOH based bag-in-box.
TECHNOLOGIA JSC is an experienced laminated materials producer. Our metallized bag-in-box are made of a high quality triplex, which serves as a barrier layer and consists of metallized PET laminated on both sides with a dense polyethylene film.
For our metallized bag-in-box, we choose met PET for the following reasons:
- Optical effect. Bag-in-box based on met PET demonstrate high gloss level that helps achieve stronger metallic shine and mirror effect, which is
an excellent protection against sunlight. - Barrier effect. Bag-in-box based on met PET is an ideal solution, when food preservation and freshness play vital role. This material prevents
the O2 penetration, which extends the product shelf life and keeps its initial nutritional value. - Visual and mechanical effect. Bag-in-box based on met PET are stronger, more tear resistant. They are less sensitive to corrosion and more flexible. Besides, in comparison to aluminum foil based bag-in-box, they are lighter, which turns this solution into more cost effective one in terms of transportation.
Lately, the world has become more concerned about anthropological impact on our planet. We are continuously searching for the ways to balance between environmental health and innovation.
