Raw Materials:

Up North uses only premium grade polyethylene resins to produce these demanding products.

Quality Control:

All resins and additives are tested and must meet stringent standards before being processed.

During Production - An extensively trained quality control team performs continuous testing to insure that industry standards are met.

After Production - Additional testing is done on production samples in Up North's in-house laboratory before products are released for shipment. Product improvement is an on-going process on test farms and sites throughout the U.S. This allows Up North to progress with today’s high-tech industry demands.


All of Up North's products are designed to withstand the normal effects of sunlight and wind brought on by exposure to the elements. So whether your feed is being covered or bagged, look to Up North for durability and quality.
