Features: Using a special formula process, the transparency reaches 92%, the elongation rate is>200%, the puncture resistance is>8N; the oxygen permeability is ≤ (cm/(m24h0.1MPa)). Advantages: Under vacuum, it can fully fit the product contour, achieving 360 ° three-dimensional display. In low temperature environments, it can inhibit the growth of aerobic bacteria, extending the shelf life of fresh meat by 15 days. It supports partial opening and secondary sealing, making it convenient for consumers to consume in batches.
