American Made Strip Curtains

Strip curtains, also known as strip doors, plastic flaps, cooler flaps, and plastic door flaps are critical for ensuring a food producing facility keeps their products fresh, their coolers cool, and their energy consumption to a minimum. Any restaurant, grocery store, convenience store, bakery, produce distributor, seafood processor, and drink manufacturer will tell you that they are necessary to keep products fresh, costs down, and equipment running longer.


The doors are critical for making sure coolers can maintain their temperature while deliveries are being made and while employees are retrieving ingredients for making food. If the cooler door is open and a strip curtain is not installed, the cooler temperature can rise 20 degrees within 15 minutes due to a lack of barrier between the warm air outside and the inside of the cooler. It can take hours to bring that cooler temperature back down to the proper levels after the temperature has risen due to the door being left open. Therefore, the strip doors are necessary for every business that needs to refrigerate their foods.

They can pay for themselves in as little as two months, through energy savings and reduction of food spoilage. There is nothing worse than throwing away product that has not been consumed due to negligence and a lack of preparation for daily business activities. Plastic curtains are also necessary for reducing outside debris and other environmental materials from entering a facility.

This type of doors can be installed inside of exterior roll-up doors to insulate a business, keep birds from flying in, and prevent dust and other contaminants from entering the space. This is especially critical for major produce, seafood, bakery, and food manufacturers that load large amounts of food on pallets for trucks to deliver to restaurants, grocery stores, supermarkets, meat markets, and anyone else that sells these products.
