One one the main reasons we are excited to offer Poly Shrink Bag is because they are product contact. Our PVC shrink bags can not come into direct contact with food products. We have always offered polyolefin center fold shrink wrap rolls, but the bags are often times easier and more efficient to use. We currently have several clients that use a centerfold polyolefin shrink wrap to wrap food products. Without an L-Bar sealer, sealing centerfold shrink wrap can often be tedious and time consuming.
