FeedFresh® Reinforced Oxygen Barrier (1-Step) Silage Cover is providing incredible value and profit to dairy and cattle operations across the country through superior strength and oxygen-blocking protection for maximum forage freshness.

FeedFresh® is a ten-layer reinforced extrusion welded laminate. The outer layers are produced from flexible high-strength premium polyethylene resins for optimal performance. FeedFresh® is produced with the latest in barrier technology and contains an inner layer of EVOH barrier resin to provide a virtually zero oxygen transmission rate.

FeedFresh® outer layers include carbon black (black side), and UV and thermal stabilizers (white side) to increase outdoor longevity. FeedFresh® is reinforced with a high denier scrim laid in a diagonal pattern spaced 3/8˝ apart with an additional machine direction scrim every 9˝ across the width to provide uniform tear resistance and excellent durability.

FeedFresh® OTR silage covers help both dairy and cattle producers to increase their bottom line, by maintaining high quality silage throughout the bunker for additional pounds of milk and increased weight gain-per-day.


Input cost to harvest and store silage continues to rise, dramatically increasing the value of forage. When it comes to silage covers, FeedFresh® is no ordinary cover. It can significantly reduce feed waste by minimizing the amount of oxygen passing into the pile to preserve feed value. When the oxygen transmission rate (OTR) value is lowered, the silage will remain in a stable condition throughout the pile. FeedFresh® provides impressive results, by substantially lowering oxygen transmission and increasing overall value with a one-step installation. Basically, the lower the OTR, the fresher the feed-see how FeedFresh® compares!


FeedFresh® silage covers can help Dairy and Cattle Producers increase their bottom line by maintaining high quality silage throughout the bunker. By improving palatability results and increasing consumption through a more consistent feed intake, cows can produce additional pounds of milk for dairy producers and steer/heifer's can increase gain-per-day for cattle producers. Raven's exceptional 60 year history of product innovation, ISO 9001 certified management system, and our highest level of customer service and support, provide even more reasons to look to Raven for all your agricultural covering needs.

Prior to using FeedFresh® silage covers, we bagged hay/age and built roll-over hay/age piles, in both cases we experienced a fair amount of mold. The hay/age we covered with FeedFresh® silage covers was pristine. The pile covered with FeedFresh® is by far the best hay/age pile we have ever had at Cornerstone Dairy. Previously we consistently had four plus inches of moldy corn silage on our piles that needed to be removed prior to feeding. Since switching to FeedFresh® silage covers, we have experienced our cleanest corn silage ever, free of any mold, enabling us to feed out the entire pile. Other bonus factors when using FeedFresh® silage covers are the reduced labor required to deploy this oxygen barrier cover as it is available in one large piece, it is reinforced to withstand installation abuse and holds up to the punishing sun. After experiencing the impressive performance of the FeedFresh® silage covers, there is no compelling reason for us to ever switch back to the old way of covering silage!
