Vacuum sealing removes air from the package before heat-sealing the bag closed. This creates an oxygen-free environment that dramatically slows the oxidation process responsible for spoilage, discolouration and off-flavours in food products. For pharmaceuticals and medical supplies, the oxygen barrier prevents degradation of active ingredients and maintains product efficacy.

The laminate nylon construction provides a secondary barrier against moisture vapour transmission. This prevents freezer burn in frozen products, stops dried goods from absorbing ambient humidity, and protects hygroscopic pharmaceuticals from moisture-induced degradation. The combination of oxygen and moisture barriers can extend product shelf life by 3 to 5 times compared to standard packaging.

These bags work with both chamber vacuum sealers (commercial grade) and external clamp-style vacuum sealers. The smooth LDPE inner layer ensures complete air evacuation before sealing. For sous vide applications, the bags withstand extended cooking times at temperatures up to 85°C without compromising seal integrity or leaching chemicals into food.

Single-layer polyethylene vacuum bags offer basic protection but have limited barrier properties and puncture resistance. Laminate nylon bags combine the heat-sealing properties of LDPE with the strength and barrier performance of nylon. The nylon outer layer provides puncture resistance against bones, sharp edges and rough handling. It also delivers superior oxygen and moisture barrier properties that single-layer bags cannot match. For applications requiring extended shelf life, product protection during transport, or pharmaceutical-grade storage, laminate nylon bags provide measurable performance advantages that justify the modest price difference.

Yes. These laminate bags work with both chamber vacuum sealers and external clamp-style vacuum sealers. They also work with standard heat sealers for non-vacuum applications. The smooth LDPE inner layer ensures efficient air evacuation during the vacuum cycle.

Yes. The laminate construction withstands extended cooking times at sous vide temperatures up to 85°C. The bags maintain seal integrity throughout cooking and the BPA-free materials do not leach chemicals into food at cooking temperatures.

Vacuum sealing in laminate nylon bags typically extends shelf life by 3 to 5 times compared to standard packaging. Actual results depend on the product, storage temperature and handling. Frozen vacuum-sealed products can maintain quality for 2 to 3 years without freezer burn.

Yes. Custom sizes and printed bags are available for bulk orders. Contact Zeropac with your specifications and quantity requirements for a quote. Lead times apply for custom orders.

Laminate bags combine the sealing properties of LDPE with the strength and barrier performance of nylon. This provides higher puncture resistance, better oxygen barrier, and superior moisture protection compared to single-layer polyethylene bags. The difference is most noticeable when storing products with sharp edges, bones, or requiring extended shelf life.

Yes. These bags are pharmaceutical-grade certified and suitable for storing medications, medical supplies and pharmaceutical products. The high barrier properties protect moisture-sensitive compounds. The clear material allows visual inspection without opening the sealed package.

Store unused bags in a cool, dry location away from direct sunlight. Keep the carton sealed when not in use to protect bags from dust and humidity. Under proper storage conditions, bags have a shelf life of 24 months from manufacture.
