    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.

Cut the edge materials reserved in the previous process, mostly used in the processing of composite film and other materials.

   Barrier property is the most important characteristic of packaging materials. In particular, the shelf life of food is highly dependent on the barrier property of packaging materials. The so-called barrier material refers to the standard state (23°C, 65% relative humidity). A 25.4-micron-thick film is a material whose oxygen permeability is below 5ml (㎡.d) and moisture permeability is below 2g/(㎡.d).

Seal failure occurs when certain factors prevent the areas that should have been joined through heat sealing from properly bonding. The common causes of seal failure are as follows:

Abstract: After stretching process, the PE film has greatly improved the tensile strength, straightness, light transmittance, haze, barrier properties. This article introduces three type PE stretched films with different processes, including casting MDOPE film, blow MDOPE film and BOPE film.

CPP film is a non - tensile, non - directional polypropylene film, comparing with polyethylene, CPP film have below characteristics:

Printing serves as the primary means for communication between products packaged in composite flexible packaging and consumers. The main printing methods for flexible packaging are gravure printing and flexographic printing.

Composite flexible packaging materials are widely used in food packaging with various types and different packing requirements.
