Abstract: This article introduces the performance characteristics and application prospects of multi-layer co-extruded high barrier films, and make a point that the multi-layer cast film performs excellent barrier properties, mechanical properties, stretch forming properties and heat sealing properties, as well as advantages of low production cost, simple process, low energy consumption and high production efficiency, which meets the requirements of environmental protection and has good development and application prospects.

On June 21^st, 2019, our CEO Mr. Chen Qicai together with the managers of each departments and workshops visited MONALISA GROUP CO., LTD and study its excellent management culture. After visiting, our management team shared with each other what they had learned from this visit.

The board members playing a positive leading role were the first ones to make contributions. After that, many employees also donated money to contribute to the fight against the virus.

       In the case of low heat sealing temperature, although the heat sealing strength is low, it can meet the requirements of use, the pouch is not damaged during the drop test;

Puncture refers to a through-hole or crack in the packaging material, particularly during the production of three-side seal pouch, caused by external force or pressure. This defect significantly affects the packaging integrity, leading to issues such as air leakage during inflation, failure to achieve proper vacuum sealing, and leakage in the containment of liquid products.

    The smell of food, beverages, cosmetics and other products has an important and subtle role, and every detail change in composition will have a greater impact on its quality. Products often transmit gases or odors to the surrounding space, and do not absorb undesired odors or aromas from the surrounding environment, and often the loss of a small amount of aromatic compounds can cause a great impact.
