Heavy Duty Sack
Package integrity for heavy, large and other demanding applications
If you have ever picked up a bag of mulch or dog food in a sack that looked the worse for wear, you understand the importance of exceptional creep resistance (the ability to resist distortion over time) and toughness. Our heavy duty sack (HDS) resins and film structure designs help these products make it from the manufacturer to the consumer’s home – with all the stops in between – in great shape.

Heavy Duty Performance
Resin performance and structure design are especially critical in the demanding heavy duty sack market. We collaborate with our customers to help them develop cost-effective heavy duty packaging that can withstand the rigors of the supply chain and meet the other requirements of each application – starting with the BONFIRE® film development platform, our proprietary suite of tools for designing and improving complex multilayer films.
Our slate of performance resins are designed for consumer and industrial multi-wall sacks with a capacity of 10 to 100 lb, with the performance properties, quality and consistency, and processability needed in heavy duty sack applications:
- Creep performance to preserve package form and reduce package failures.
- Exceptional stiffness and toughness to help maintain the shape and design of a package, resist abuse and provide optimal seal integrity. Our HDS resins help to protect the contents of each package from external contamination and resulting waste and spoilage, especially for pet food and institutional food service applications.
- Seal integrity to ensure seal through contamination such as dust and other fine particulates.
- Enhanced barrier through multilayer film structures that preserve large-format food packaging and specialty chemicals
- Structure design expertise for packaging that includes recyclate.
- Beautiful appearance qualities for shelf appeal and branding.

Packaging Makeover: Delivering Recyclability Without Trade-Offs
A leading premium pet food brand set out to make its packaging more recyclable without compromising the performance, quality, or shelf appeal consumers expect. Working together, we reimagined a traditional multilayer structure into a fully recyclable polyethylene solution, designed to protect sensitive pet food products from moisture, oxygen, and grease while maintaining durability, high-quality graphics, and cost efficiency.
The result is a high-performing, monomaterial package enabled by our advanced resin technologies, including SURPASS® HPx267-AB resin. This innovative structure delivers exceptional barrier performance and preserves product freshness, while meeting recyclability design guidelines and reducing overall material costs by approximately 10%. By combining recyclability with performance and aesthetics, this solution helps brands move closer to circular packaging goals—without trade-offs.
