1, the type of shrinking machine: a wide variety, I introduce several common materials on the division: PE shrinking machine and POF, PVC shrinking machine. The model is similar, the principle is the same. Manufacturers need to choose the appropriate shrinking machine model according to the customer's packaging requirements and product characteristics. The shrinking machine is divided into three main mechanisms, a heating mechanism 2, a blowing mechanism 3, and a conveying mechanism. These parts have interrelated factors.
2, the application of shrinking machine: in the field of packaging has a very important position, the shrinking machine is widely used, suitable for: printing, hardware, home, electronics, food, pharmaceutical and other industries. The shrinking materials used in general shrinking machines are PVC, POF, PE, and the like. At present, POF shrink film is the most widely used, and it is recognized and used by many manufacturers with its good transparency, strong shrinkage, high arbitrariness and especially environmental protection. It can also be called an environmentally shrinkable film. So there are so many fields of use. The chemical name of PVC shrink film is: polyethylene is a toxic material that is not environmentally friendly, has low self-willedness, and is gradually replaced by POF. Generally applicable to chemical non-environmental industries. PE shrink film is generally the most widely used in the beverage industry. Its characteristics: poor transparency, good arbitrariness and strong tensile strength are suitable for heavy shrink film packaging. Suitable for large-volume automatic shrink packaging of cans, glass bottles, beer, mineral water, etc.
Organic spirulina powder is extracted from 100% natural spirulina. Spirulina is neither an animal nor a plant, it is actually a natural freshwater alga. Its protein content is incredibly high. It also contains iron, vitamin B6, and several other micronutrients. Ensuring that micronutrient intake is maintained is very important to ensure optimal physical condition.
