How does air valve design affect the shelf life of coffee?
The design of air valves mainly affects the shelf life of coffee by controlling gas exchange, maintaining packaging integrity, and reducing oxidation reactions, as follows: Precise control of gas exchange Emissions of carbon dioxide: Coffee continues to release carbon dioxide for a period of time after roasting. If there is no air valve, excessive accumulation […]
Difference between flexographic and gravure printing
Flexographic printing (flexgraphic printing) and rotogravure printing are two common printing processes that differ significantly in several ways: Principles of Printing Flexographic printing: The use of a flexible raised image printing plate, usually made of rubber or polymer. Ink is transferred to the raised portion of the plate, and the ink is then transferred directly […]
What role does aluminum foil play in food packaging bags
With the increasing richness of life, the types of food are also enriching …… different types of food its packaging is also different. Food packaging bags can help food to extend the shelf life, and for some different materials to achieve the preservation effect is different. Food packaging is commonly used in aluminum foil bags, […]
What is the sealing of packaging bags related to?
Packaging Materials Material characteristics: Different packaging materials have different barrier properties. For example, the compactness of the molecular structure of plastic film and the type of polymer can affect its ability to block gases, water vapor, and other substances. Like polyethylene (PE) film, it has certain flexibility and moisture resistance, but relatively poor oxygen barrier […]
Application status and development trend of intelligent packaging in the food and beverage industry
Information Awareness and Traceability: Widespread Use of Barcode Technology: Barcode is one of the smart packaging technologies that have been used early and widely. In the food and beverage industry, almost all products have barcodes, which can be scanned to obtain the basic information of the product, such as the name, specification, and date of […]

Pocket lightweight bags are small, lightweight and easy to carry bags that usually have the following features and application scenarios: Features Compact size: generally designed to fit easily into pockets, backpacks or handbags, etc., without taking up too much space, making it easy for consumers to carry around. Light weight: Using lightweight packaging materials, such […]
How the craftsmanship and convenience of packaging affects purchases
The process and convenience of food packaging has an important impact on the consumer’s purchasing decision and experience, the following are some common packaging processes and their embodiment in the convenience: Easy-open process Tear Line: Setting up a tear line on the bag is a common easy-open process. By pre-cutting a weakened line on the […]
Why do multilayers delaminate? What can we do?
Delamination in multilayer materials, whether in packaging, coatings, or composites, refers to the separation of those distinct layers. This failure can occur due to a variety of factors, often involving stresses at the interfaces between the layers. Here’s a breakdown of the common causes: Inadequate Adhesion Poor Adhesive Quality: The adhesive used to bond […]
Commonly used surface treatment technologies for packaging materials
“Surface treatment technology” refers to the process of artificially forming a layer on the surface of the substrate material with different mechanical, physical and chemical properties from those of the substrate, to meet the corrosion resistance, abrasion resistance, decorative or other special functional requirements of the product. Different processing techniques, applicable materials are different. There […]
