SealFresh™ is multi-layer non-reinforced 2 mil clear oxygen barrier offering a low-weight to high-strength ratio designed for high flexibility and ease of installation. SealFresh™ oxygen barrier film is the first step in this 2-step silage covering system designed to prevent oxygen from reaching the feed while preserving valuable nutrients. SealFresh™ is the base layer placed directly against the pile, just below the primary exposed cover. The second step in this system utilizes Raven’s tough Dura-Skrim® string-reinforced cover, designed to block UV rays and provide long-term durability. Raven also offers an alternative outer cover, called FeedPro-G, in a white/black non-reinforced option that incorporates recycled resins in the core layer as an economical solution. SealFresh™ oxygen barrier is formulated to be flexible and conforming for easy installation — with an accordion-folded roll configuration to optimize deployment.
SealFresh™ is designed to cling to the silage pile for peak fermentation conditions and stabilize the forage to reduce dry matter losses; this allows for maximum feed forage freshness.
SealFresh™ (2-Step Cover System) - Step #1 - Non-reinforced 2 mil Oxygen Multi-Layer Barrier. Step #2 – Dura-Skrim® 6 mil black/white string-reinforced outer cover.
Raven SealFresh™ provides a virtual seal to promote optimal fermentation conditions and stabilizes the forage to substantially reduce dry matter losses and ultimately increase bottom-line profits.
INCREASE FORAGE FRESHNESS
Seal Fresh™ is part of a 2-step silage covering system and is placed just below the primary exposed cover directly against the pile. SealFresh™ Oxygen Barrier is formulated to be lightweight and pliable to easily conform and cling to forage surfaces. The surface is protected and SealFreshr™ prevents air pockets from forming under the cover to maximize forage freshness. Seal Fresh™ provides a virtual seal to promote optimal fermentation conditions and stabilize the forage to reduce dry matter losses and ultimately increase profits.
COMPARE LEADING OTR FILMS
Compare SealFresh™ against other leading oxygen barrier silage covers on the market. The graphs below show the amount of oxygen at a 21% concentration (ambient air) that passes through the barrier film in CC/M2/Day units. SealFresh™ EVOH barrier technology produces an extremely low oxygen transmission rate of 1.6 CC/M2/Day! This value equates to SealFresh™ blocking two-times more oxygen than the leading competitor and blocking over 18 times more oxygen than the second leading competitor.
OXYGEN TRANSMISSION RATE: (CC/M2/24H)
SealFresh™ Compared to two leading barrier films for covering silage according to ASTM D-3985/DIN 53380-3 at 21% Oxygen Permeability.
The 7-layer construction of SealFresh™ provides for improved strength and tear resistance in an ultra-light 2.0 mil film to withstand installation and conform to uneven surface irregularities. SealFresh™ provides easy installation with an accordion-folded roll configuration to optimize deployment.
