The Pratt EZ4X5.5 polyethylene E-Z bubble seal pouch, 5-1/2" x 4", is made of clear polyethylene bubble cushioning material with a 3/16" bubble height for protecting delicate and fragile package contents during shipping. This pouch has a 1" deep folding lip with adhesive tape to permanently seal the pouch. The polyethylene is clear to show package contents before unwrapping, and is made with 15 percent post-industrial recycled content. This pouch comes in a carton of 1,000 for commercial applications. The pouch measures 5-1/2" x 4" (L x W). (L is length, the horizontal distance on the longest side; W is width, the horizontal distance on the shortest side). Bubble packing is a cushioning material used to protect items from damage and rough handling during shipping. It has two layers of plastic film with regularly spaced air-filled bubbles on one side. Typically wrapped around breakable items and held with tape, it is also available with cohesive or adhesive coatings to stick to itself or to the protected item. Bubble wrapping can generate static electricity through friction during shipping, so it is also available with an antistatic coating for use with sensitive electronic products. Pratt Industries manufactures recycled packaging and display solutions. The company, founded in 1948, is headquartered in Conyers, GA.
