According to the Animal Feed Industry Association (AFIA), the US animal feed industry produced over 280 million tons of animal feed, generating approximately $267 billion in sales in 2023. Animal feed is a burgeoning market and is expected to grow to $181 billion by the year 2034, with a compound annual growth rate (CAGR) of 4.4%.
With more than 5,600 manufacturing facilities nationwide, there's a constant need for reliable animal feed bagging and packaging solutions. But should you choose woven poly or paper feed bags for your business? Below, we compare woven poly blend and paper bags on factors such as strength, moisture protection, and shelf appeal. Southern Packaging provides an extensive range of packaging solutions for the animal feed industry, including multi-wall paper bags, woven poly, BOPP (biaxially-oriented polypropylene), and paper-poly laminate bags.
Animal feed packaging is far more than just a container; it's a critical element that directly influences a product's integrity, shelf life, and how customers perceive it. Feed bags protect their contents, preserving freshness, preventing damage, keeping pests out, and guarding against external factors like moisture, light, and contaminants. This protection can extend a product's shelf life, ensuring it reaches the end user while it’s fresh and that it stays fresh longer.
Beyond its functional role, packaging is a powerful branding tool. Its design, color, and materials create a first impression that shapes customer perception of quality, value, and brand identity. A high-quality, durable package can convey a sense of reliability, while a flimsy or poorly designed one can harm a brand’s identity. Today's market is seeing an increasing demand for packaging that meets a complex set of criteria: it must be durable to withstand the rigors of shipping and handling, visually appealing for effective branding, and compliant with a growing number of industry standards and sustainability regulations.
Woven polypropylene (WPP) bags are made from a synthetic plastic polymer called polypropylene. To create the bag, polypropylene resin pellets are melted and extruded into thin films, which are then cut into tapes. These tapes are woven together on a circular loom to create a durable, fabric-like material. This woven fabric is then cut and sewn into bags.
Woven poly bags are a popular choice for packaging a wide range of animal and livestock feed, including cattle, poultry, horse, and pet food. They are popular for several key benefits:
Multi-wall paper bags are a packaging solution made from multiple layers of kraft paper. This layered construction provides strength and is often enhanced with a polyethylene (PE) liner or a film between the paper plies to offer additional protection. Multi-wall bags are designed in various styles, such as pasted valve and sewn open-mouth, to accommodate different filling and sealing methods.
The bags are a popular and cost-effective option, especially for packaging products that require a biodegradable solution. Their multi-wall construction makes them suitable for use in dry environments where the contents need protection from external elements without the need for significant moisture barriers. However, a limitation of standard multi-wall paper bags is their lower tear resistance and moisture vulnerability compared to woven polypropylene bags, which can be a drawback in humid conditions or during rough handling.

When it comes to choosing the best bags for your animal feed business, consider your product’s storage requirements, your distribution strategy, and your budget. Woven poly bags, while more costly up front, offer greater tensile strength, moisture-resistance, and reusability. Multi-layered paper bag options are best suited for smaller, drier, short-term applications where biodegradability is a priority.
