Polypropylene outer envelope PRO for vinyl LP - 10 pieces

Beautiful envelope of excellent quality POLYPROPYLENE, designed and built for LPs with OPENING cover both single and double, glossy 90my thickness crystal type extremely transparent. Not to be confused with polyethylene bags, a more opaque, softer and cheaper material. Polypropylene is a material with a "memory" effect, ie it tends to return to its original position (flat sheet) therefore the envelope, when compared with polyethylene, tends to appear rather rigid and tends to remain straight. The end result is a really beautiful, shiny, very thick and resistant envelope.

The transparent envelope fits perfectly and covers the entire surface of the gatefold cover, both internal and external. Product difficult to find on the market.
