Why Walter Solutions
Canadian-based project management
Your project is managed from British Columbia, Canada: structure review, sampling, testing and production follow-up with one accountable point of contact.
U.S.-patented high-barrier film technology
The high-barrier film behind our PE/PE structures is covered by U.S. Patent No. US 12,097,686 B1, held by our manufacturing partner.
See the patentOTR/WVTR and food-contact documentation available
Barrier test data (OTR, WVTR) and food-contact documentation are shared per project on request, matched to your structure and test conditions.
Technical resourcesSampling, filling-line trials and production support
From prototypes and filling-line trials on your equipment to commercial production and QC.
How conversion worksStructure, made clearer
Our main option. PE-based, high-barrier structures designed for recycling, suited to most dry food, pet food and snack applications.
A premium option for demanding conditions. PP-based, high-barrier structures keep their barrier performance stable under high temperature and humidity. Higher cost, recommended for high-end products or applications where heat and humidity performance matters.
How the transition works
Analyze the existing bag, product, shelf life and filling conditions
Recommend suitable PE-based structure, barrier and format
Prototypes; OTR, WVTR, seal and transport testing
Validate speed and seal on customer equipment
Customer validates actual product shelf life
Artwork, print, production and QC
Built for demanding categories
Pet Food & Treats is a featured industry.

Recyclability notice
Recycling acceptance and collection methods vary by province, municipality and recycling program. A package described as “designed for recycling” has been developed with material compatibility in mind but may not be accepted in every local collection system.
