Choosing the Right Feed Bag: Woven Poly or Paper?
According to the Animal Feed Industry Association (AFIA), the US animal feed industry produced over 280 million tons of animal feed, generating..

BOPP bags offer the superior appearance and performance characteristics you need to market your premium deer corn and wildlife feed products during hunting season.
Biaxially Oriented Polypropylene or BOPP is a flexible material derived from melting and biaxially orienting (stretching on both axis) a polypropylene polymer. The process of biaxially orienting polypropylene, stretching it in the machine direction and transverse direction, improves the films physical properties, such as water vapor barrier, stiffness, dimensional stability, and optics.

What is an Open MouthBag? Open mouth plastic bags are a common packaging style that are factory closed on one side, and closed by customer sealing/sewing on the opposite side. The materials, construction, and characteristics of open mouth bags vary widely, making them suitable for diverse applications ranging from animal feed to construction products.
BOPP bags can be printed in up to 10 colors using process printing methods. Engaging graphics capabilities range from simple to photorealistic.
BOPP bags are made with high strength woven polypropylene (plastic) tapes. The inherent strength of the bag’s construction prevents breakage and product loss.
BOPP bags are effectively waterproof. The woven tapes are laminated with a layer of film to make the bag nearly impermeable. Paper bags aren’t even comparable when it comes to the water/moisture resistance of a BOPP bag.
BOPP bags can be printed so that the gusset remains clear, allowing your customers to see the product inside without having to open the bag.
Polypropylene plastic is unaffected by grease resulting in a clean, easy to handle package. No one wants to carry a smelly bag in their truck! BOPP bags are designed to prevent odor from escaping the bag.
BOPP bags are made from 100% recyclable plastics. Multi-wall paper bags with a film layer cannot be recycled.
While BOPP sewn open mouth bags remain one of the most popular packaging styles for premium wildlife feed and deer corn, many large feed producers also use woven poly block bottom valve bags for high-speed packaging operations.
Both bag styles offer strong moisture resistance and durability, but they serve different operational needs.
Open mouth bags are typically:
Valve bags are designed for:
Manufacturers packaging high volumes of deer corn or wildlife feed often evaluate both styles depending on their production equipment and distribution model.
A woven poly “block bottom” or “valve” bag is a common industrial packaging style designed to package a wide variety of dry flowable products. Valve bags are packed on equipment that deposits material into the bag via a horizontal filling spout. After filling, forces generated by the product inside the bag allow the valve opening to self-seal.
Valve bags can be made with paper, woven poly, or poly film. Woven poly bags are made by extruding polypropylene resin into sheets, cutting the sheets into tapes, and weaving the tapes into tubular fabric. The tubular fabric is then laminated, cut, and converted into a finished bag.
Woven poly valve bags offer several functional advantages over traditional multi-wall paper bags, particularly in high-volume feed applications.
For feed producers operating automated packaging lines, woven poly valve bags provide several operational and logistical advantages beyond standard BOPP open mouth bags.
Woven poly valve bags use tubular woven polypropylene construction without a back seam, making them highly resistant to rupture, tearing, and product loss during transport.
Valve bags are designed specifically for high-speed automated filling equipment and require no additional sewing or sealing after filling.
The combination of woven polypropylene and laminated film creates a nearly waterproof package that performs well in outdoor, agricultural, and humid storage environments.
Unlike some traditional printed packaging, woven poly valve bags can utilize advanced print technologies that resist scratching and fading during transport and pallet handling.
Woven poly valve bags are significantly lighter than multi-wall paper bags. In many cases, manufacturers can store and transport substantially more empty bags per pallet, reducing freight and warehouse costs.
Like BOPP bags, woven poly valve bags are made from recyclable polypropylene materials, making them a more sustainable alternative to laminated paper packaging that cannot be easily recycled.
Poly woven valve bags are often less expensive than traditional 3-ply Kraft paper valve bags while offering superior moisture resistance and durability.
Selecting the right wildlife feed packaging depends on:
Many large feed and agricultural manufacturers use a combination of both packaging styles depending on product type and sales channel.
