One Source for Multi-Wall Bags
For decades, Portco Packaging has been a leading provider of multi-wall bags for a variety of industries, including feed and seed, potato and food processing. Our multi-wall bags are manufactured to fit your specifications in size and paper as well as custom printing and design.
Portco’s multi-wall bags feature solid construction, reliable materials and consistent quality. Our bags are made tough to withstand the rigors of shipping, processing and end use handling. At the same time, we know that economy of construction is important to your bottom line. That’s why we recommend the right bag — one that’s not too heavy, not too light — to adequately contain and protect your product.
Custom Packaging
Choose up to 4-ply construction in poly-lined, sewn-open-mouth (with sewn-in handle available), tape-over-sewn seals, square bottom, pasted valve, or pinch-bottom bag styles. Hang-Guard wicketed baler bags are available to improve packaging efficiency.
Our top-of-the-line metal detection process is an added safety assurance for food processors.
Custom printing and design
Portco offers eight-color flexographic printing services complemented by a skilled design team who help create an unique identity for your product or a compelling concept for your package. Our flexographic specialists also ensure your art reproduces on the bag just as you envision it in your mind.
