PVDC High Barrier Shrink Bag is a kind of Barrier Bags, which uses PVDC as the oxygen barrier. Pvdc Shrink Bag can greatly extend the shelf life of food, especially fresh meat. Tipack uses the core multi-layer co-extrusion technology to make the shrink bag, which fundamentally avoids the use of adhesives and makes the product safer.
About Tipack
The core technology of Tipack is multi-layer co-extrusion high-barrier material technology, which can achieve the best matching of various material properties, meet the needs of safety, convenience, nutrition, and deliciousness required by food and other packaging, while completely avoiding the solvent of traditional packaging. Residue, high energy consumption, poor strength, poor transparency and other problems. The main application fields are: fresh meat, prefabricated food, soft canned food, capsule beverage, dairy bakery, quick-frozen food, cooked food takeaway, high barrier sheet, etc.
The advantages of multi-layer co-extrusion:
· Strong functionality
In multi-layer co-extrusion, materials with different properties can be combined according to needs, so that they have different functions of multiple materials at the same time. For example, the use of PE material in the inner layer will make the packaged product have good heat-sealing performance and mechanical properties; the use of EVOH/PVDC barrier material can effectively block oxygen and water, prolong the shelf life of food, and effectively lock in freshness.
· Lower cost
The multi-layer co-extrusion high-barrier material technology is a multi-layer co-extrusion one-time molding process, which does not require traditional composite, coating and other post-processing processes, which can effectively reduce raw material costs and production processes, not only save production costs, but also control the thickness of packaging materials. It is possible to achieve thinning feasibility. And to achieve the same barrier effect, due to the simple process, the cost of the produced product can be reduced by 10%-20% compared with the composite product.
· Other advantages
Safe and environmentally friendly green packaging, without any residual solvent, to avoid food safety problems; it can be used for low temperature freezing at -30 °C, or high temperature cooking or boiling sterilization at 121 °C; easy to print and meet various color requirements; multi-layer co-extrusion layer The more the number, the greater the advantage in thinning expensive materials; the more flexible the structure adjustment between material layers, the more applicable formulas, and the wider the range of products.
