Choose the most suitable material for your product in bag-in-box

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:

1. 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.
2. 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.
3. 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.

Metallized film is less sustainable than transparent since it is more difficult to recycle it. The waste from metallized film is generally incinerated with a toxic gas. Besides, it is never burned completely – metal is present in ashes. For those, who are more concerned about sustainability in bag-in-box production, we offer transparent EVOH based bags.

Bag-in-box made of EVOH based film has the following advantages:

1. Product inside the bag-in-box is visible; therefore, both producers and consumers can enjoy the healthy color of the content. This feature also helps the producer quickly identify the processes that could lead to
   the loss of product freshness.
2. Environmental friendliness. Bag-in-box made of EVOH film can be incinerated without the use of toxic gases. EVOH film is produced by means of extrusion, which reduces the risk of harmful emissions into
   the atmosphere.
3. Human health favorability. The production of bag-in-box based on EVOH film does not involve the application of any solvents or adhesives. Thus, it substantially reduces the risk of harmful substances migration into
   the product.
