Packaging industry creates breathable packaging

Currently there are two methods for testing breathability testing: equal pressure method and equal difference method. The isobaric detection method is relatively simple in that it can only check the permeability of oxygen and carbon dioxide, and cannot detect the permeability of nitrogen. However, the method of equal difference is different. It has no choice for the test gas and can eliminate oxygen and carbon dioxide. The nitrogen is detected outside, and the test cost is lower, and the temperature of the test environment can also be controlled. Therefore, in the packaging machinery industry, all those who engage in modified atmosphere packaging adopt this method.

For food products, it is best to maintain the original taste and freshness, but at present, it is rarely able to do this, most products are achieved through freezing to achieve this, in order to not be frozen from the packaging On the move, currently in the packaging machinery industry, some equipment has already achieved this point. It manufactures breathable packaging through advanced production technology and a combination of breathable outsourcing materials.

To make product packaging exhale, it is necessary to deoxidize it first, and desiccants, preservatives or deoxidizers are included in the food packaging, which can remove the unfavorable storage and preservation of gaseous substances such as ethylene released from fruits and vegetables and water vapor. This is mainly achieved through the penetration of gas outside the bag or the penetration of preservatives, desiccants or deoxidizers in the bag, and the action of living or physical adsorption. To achieve this effect, it is necessary to make the bag have a certain degree of permeability or to prevent leakage of substances inside the bag. In the middle, permeability is an important physical parameter in the paper packaging bags used, which can determine the usage of different packaging papers. This packaging material is rarely seen in the packaging machinery industry and is a new thing.

The idea has been followed by specific practical work, then we must choose from the packaging materials, for this type of air-conditioned packaging, we must according to the characteristics of the actual product package material permeability selection. Normally, the gas used for modified atmosphere packaging is a mixture of oxygen, nitrogen, and carbon dioxide, or a mixture of oxygen and carbon dioxide. For this purpose, oxygen permeability and carbon dioxide must be passed through the material when selecting packaging materials. Accurate testing of the permeability of nitrogen and nitrogen can not be equivalent to a variety of gases and should be distributed in equal proportions. If the distribution of unreasonable packaging material into the use of packaging machinery production line will have serious consequences.

EVA Foam Printer are widely used to print a lot of materials including acrylic, metal, wood, glass, plastic, phone covers, MDF, melamine board, foam boards, PVC boards, ceramic tiles, etc. Mirror effect, 3d effect, embossing effect and flat effect can be easily achieved.


With Fast & easy is a big advantage for digital uv printing. And another advantage makes digital uv printing popular in many fields is the printing durability.


UV Printer is a new technology, you can print custom designs which can increase added value of your crystal with competitive ability. And the colorful designs on the crystals are high fastness, excellent adhesion and waterproof. Thanks to Digital LED UV Flatbed Printers, promotional gifts such as awards, trophies, plaques, medal have personality with good reducibility and high quality.
