Mono-material based packaging is defined as a packaging having more than 95 % of one resin type like PE, PP of PET and by extension less than 5% of other material or resins. Additionally, as there is no compromise for the consumers about food safety, packaging must contain one barrier material to prevent food spoilage.
100% PP woven bags
Reverse-printed woven PP bags can be designed to be 100% PP mono-material packaging, fitting with current recyclability trends for post-consumer bag recycling.
Orevac? 18790 resin, a fluid MAH-grafted PP concentrate, can be used in dilution in a PP matrix (10-20%)?for extrusion lamination of PEI (polyethylene imine) primed reverse printed BOPP films and woven PP fabric. This specialty Orevac? resin can provide suitable bonding for high demanding applications such as pet food bags, or consumer bags.
Typical PP mono-material woven bag structures?
High barrier EVOH resin for single material based packaging
For high barrier films used in food preservation, less than 5 % of EVOH content is commonly accepted to be classified as single material. Evasin? EVOH 2951F with 29% ethylene content is a solution to decrease EVOH content below 5% in flexible packaging. This grades enables to down gauge the EVOH thickness while maintaining a high gas barrier.
?Aluminium foil replacement
The elimination of aluminium foil by oxygen-barrier?Metallized Films?is a solution to recycle snack foods bags or coffee sachets. Orevac? resins are commonly used as?Adhesion Promoters?for the metallization of BOPP, mCPP and BOPE films
