Generally, the ink manufacturer will give a reference ratio when providing the ink. At the same time, the color printing factory should make a small test before the production, if the amount of the curing agent is too small, the crosslinking degree of the curing agent and the resin is low, the adhesion strength of the ink layer, Heat resistance and hydrolysis resistance will decrease; if there are too many curing agents, excessive crosslinking will occur, affecting the crystallization and micro
As the market competition becomes more and more intense. In order to meet the needs of the market, in addition to further strengthening the quality control of printing, lamination and other processes, more and more attention is paid to the processing quality of heat-sealed bags.
Modern packaging is based on scientific analysis, calculation, rational selection, design and decoration, using advanced packaging techniques and packaging machinery. As a qualified product, in addition to the product (food) should be tested, the packaging must also undergo various tests. Such as the permeability, moisture permeability, oil resistance, moisture resistance of the packaging container, the role of the packaging container (material) and the food, the residual amount of the packaging
The packaging design should meet the geometric requirements and strive to make a larger volume container with a minimum of packaging materials, which can save packaging materials and meet environmental requirements. The structural design of the packaging container shall comply with the mechanical requirements, and the compressive strength, impact strength, drop resistance, etc. shall be in accordance with the requirements for storage, transportation and sales of the package. The design of the pa
Every step of the packaging operation should be selected, sealed, printed, bundled and labeled according to packaging standards, regulations and regulations. Standardization and standardization throughout the entire packaging process, which is conducive to raw material supply, commodity circulation and international trade, etc. Recycling and disposal of waste packaging materials should meet environmental requirements.
In order to meet the needs of food processing technology, a variety of new packaging equipment has been developed, such as vacuum packaging machine, vacuum inflatable packaging machine, heat shrink packaging machine, blister packaging machine, body packaging machine, sheet thermoforming equipment, liquid Filling machine, forming/filling/sealing packaging machine, aseptic packaging equipment, etc. According to the selected packaging materials and packaging process methods, selecting or designing
In order to extend the shelf life of food, we adopt new packaging technologies that are constantly being developed, such as active packaging, anti-mild packaging, moisture-proof packaging, anti-fog packaging, anti-static packaging, selective venting packaging, non-slip packaging, cushion packaging, etc. New technologies, China's applications are not universal, and some methods are still blank. The application of these advanced technologies can significantly improve the protection function of pac
Modern food packaging materials mainly include plastics, papers, composite materials (plastic/plastic, plastic/paper, plastic/aluminum, foil/paper/plastic, etc.), glass bottles, metal cans. Wait. We mainly describe composite materials and plastic packaging.
