PVC Blister

A flexible plastic sheet containing bubbles that are distributed evenly in the air is known as bubble wrap. It offers protection against impacts for fragile goods by acting as a cushion and shock absorber. Protective packaging made to fit a specific item is typically made of foam materials like polystyrene (Styrofoam) or polyethylene foam. To hold and cushion fragile goods, they can be moulded or made into wraps, corner blocks, or inserts. A strong yet lightweight packing material is corrugated cardboard. Between two flat layers, there is an interior layer with flutes. It may be used for boxes, dividers, and edge guards and has high impact resistance.
