Product Description
Tea bag
Polyethylene, polypropylene, polyvinyl chloride and other plastic containers have the characteristics of generous, beautiful and good packaging and display effect, but their sealing performance is poor. They are mostly used as outer packaging in tea packaging, and they are mostly encapsulated in composite film plastic bags.
Film bag packaging
Plastic composite film has many advantages, such as light weight, not easy to damage, good heat sealing, suitable price and so on. There are many kinds of composite films used for tea packaging, such as moisture-proof cellophane / polyethylene / paper / aluminum foil / polyethylene, biaxially stretched polypropylene / aluminum foil / polyethylene, polyethylene / polyvinylidene chloride / polyethylene, etc. the composite films have excellent gas resistance, moisture resistance, aroma retention, odor resistance, etc. Since most plastic films have 80% ~ 90% light transmittance, in order to reduce the transmittance, ultraviolet suppression can be added to the packaging materials or the light transmittance can be reduced by printing and coloring.
In addition, composite materials based on aluminum foil or vacuum aluminized film can be used for shading packaging. The aluminum foil composite packaging bag is made of metal aluminum. Its metal barrier performance and the practicability of composite plastic film are very strong, which basically meets the aroma preservation requirements of tea.
There are various packaging forms of composite film bags, including three side sealing shape, self-supporting bag shape, folding shape, etc. Packaging because the composite film bag has good printability, using it as sales packaging design has a unique effect on attracting customers and promoting tea sales.
The company is located in Zhongshan banfushunjing Industrial Park, 105 national highway along the central axis of Guangzhu. The new plant was broken in 2013 and put into operation in February 2014. Covers an area of nearly 10000 square meters, inside and outside the factory, clean environment. The building area is more than 9000 square meters, including 6500 square meters of main workshop and 2500 square meters of comprehensive building.
At present, the company has a number of high-speed gravure printing machines, large dry laminating machines, high-speed automatic slitting machines, multi-functional bag making machines of various shapes, and a number of test and detection instruments equipped in the laboratory.

Concept of vacuum packaging:
In vacuum packaging, the food is put into the packaging bag, the air in the packaging bag is extracted, and the sealing process is completed after reaching the predetermined vacuum degree. After the air in the packaging bag reaches the predetermined vacuum degree, nitrogen or other mixed gas is filled, and then the sealing process is completed.
Principle of vacuum packaging
Vacuum packaging refers to the extraction of all the air in the package and the packaging materials with extremely low oxygen permeability, so that the oxygen from the outside can not penetrate into the package, reducing the rate of oxidation and rancidity of fresh meat, so as to ensure the freshness of fresh meat. Fresh meat packed in vacuum can be stored for 14-20 days at 0 ± 1 ºC. After vacuum packaging, the shelf life of the meat will be longer than that of the vacuum packaging. However, if the chilled meat returns to bright red color in the presence of oxygen after removing the packaging, vacuum packaging is generally used in hotels and some hypermarkets that require long storage time and high quality.
Materials used in vacuum packaging
In addition to polyvinylidene chloride (PVDC) with good oxygen permeability and shrinkage resistance, the materials used for vacuum packaging include polyester, polyamide, or nylon, polyester film and polyethylene multilayer. Polyvinylidene chloride (PVDC) has the highest permeability to prevent oxygen and water vapor, but its biggest disadvantage is that it can't heat seal. Polyester has strong tensile strength and softness; nylon has good oxygen permeability, heat resistance and cold resistance, and strong mechanical properties, but it has high water vapor permeability and high price, so it is mostly used as a vacuum packaging material for fresh meat in the form of multilayer composite.
The function of vacuum packaging
Inhibit the growth of microorganisms to avoid external pollution;
It can slow down the oxidation rate of fat and inhibit the enzyme activity;
Reduce water loss and maintain product weight;
The package is beautiful, intuitive, and easy to carry. |
