Vacuumsealable

Vacuumsealable refers to materials or products that are suitable for packaging using a vacuum sealing process. This process involves removing air from the packaging before it is sealed, creating a vacuum. Vacuum sealing is often employed to extend the shelf life of food products by preventing oxidation and the growth of aerobic bacteria. Materials that are vacuumsealable must be able to withstand the pressure changes during the vacuum sealing process without compromising their structural integrity or the seal itself.

Commonly, vacuumsealable packaging materials are made of plastics, often multi-layered films. These films are designed to be impermeable to gases like oxygen and moisture, which are key factors in spoilage. The specific composition of vacuumsealable materials can vary depending on the intended application, such as food preservation, medical device packaging, or industrial storage. Compatibility with heat sealing is also a crucial characteristic, as the vacuum sealing process typically concludes with a heat seal to maintain the vacuum. Products that are not suitable for vacuum sealing may be too porous, too brittle, or contain components that can be damaged by the absence of air.
