Silage Wrap and Barrier Properties

The commercial use of silage wrap (or stretch wrap) is growing fast. This industry has developed from almost negligible manufacturing activity to a significant one with new processing lines and new processing equipment in just the last five years. In 1995, there an estimated 250 to281 tonnes of silage-plastic wrap material being used alone. This is a relatively small percentage of all wrapping paper used worldwide.

UV woven silage-plastic wrap is made using polystyrene, polyurethane or UV treated cellulose. The urethane is cured using a procedure that is called cross-flow curing. This cured urethane is then draped over the surface to be sprayed with reflective white paint. The spraying process is done after the roll has cured completely. This type of silage wrap has been around the longest. It first came into use in the United States aboard cargo ships.

Another form of the silage wrap is the regular one mil 30 reflective white polyethylene film for silage wrap. These films provide greater UV protection and are more convenient than the rolls. They are thicker than the rolls and provide better coverage than the standard one mil 30. While regular one mils 30 films will go on smoothly and without wrinkles, the thicker films will have more pronounced wrinkles in the corners of the eyes and the areas where the hairline meets the forehead. This type of film also provides greater UV protection. When the film is used with self-adhesive spray mounts, the mount will adhere to the hairline and provide adequate UV coverage.

The final type of silage-plastic wrap we will discuss is the clear wrap. This film is composed of a clear plastic base that contains an aluminium oxide layer. The aluminium oxide layer provides a clear viewing window similar to that seen with tinted glass. The clear wrap can provide up to three times the amount of coverage as the regular one mil 30 and can be used for six months of outdoor storage.

Hay provides a barrier property that can completely block the sun’s heat and light. Its superior strength and durability make it an excellent material for constructing all kinds of buildings and homes. Its wide range of uses allows it to be used for roofing systems, flooring options, partitions, and much more. If you are looking for high UV resistance, high impact resistance, and high abrasion resistance and want to add an attractive coating to your building or home, this is the ideal product. You’ll find that it is easy to care for, requires very little upkeep, and creates a barrier that will keep the elements out.
