The packaging of milk in North America is very different from Europe. In North America, a large amount of milk is used by cars, and it is selected and distributed to every household and used in a container for each household. A small amount of milk is packed in glass bottles, and the glass bottles are recyclable. However, this kind of packaging is not suitable for sale in supermarkets and food stores. The glass bottles are too heavy, fragile, and lack proper seals. In the 1940s in Maine and Canada, light-weight cardboard non-recycled cardboard boxes were used to pack milk. The original cardboard boxes were made of waxed cardboard. With the current standard rice, the sealability is poor. There is a leak, milk sometimes has a waxy smell. In the 1960s, paraffin wax was replaced by LDPE, which can solve the problem of desire and waxy smell. At this time, the beginning of packaging milk in glass bottles is gradually reduced, because the carton packaging of milk is disposable , It is not recycled and reused, it is more convenient, lighter in weight, and has low transportation costs, and is not easy to break. It is loved by people, and the milk in glass bottles is modified. Blow molded HDPE and LDPE jars, with the cost gradually approaching coated cardboard, replacing other milk packaging, especially 3.785L (1 plus warehouse) weight packaging size, plastic jars are more suitable for children Heavy use, so far, covered cardboard boxes are still being used on milk packaging below 1.892L. (Half a gallon) because of the lower cost and better acceptance of the environment.

In the 1960s, PE film was used to form the filling and sealing machine for the bottom, and the top was sealed in the milk tube bag packaging, which gradually replaced the plastic film for packaging. The PE film was used as the packaging material for the continuous filling machine for the forming, filling and sealing machine. When packaging body products, heat sealing is not a problem, because it does not contaminate the heat cover, but the milk used in the liquid is very contaminated by Rong County, which affects the heat seal fastness and heat seal reliability. The size of most bags is three small packages and then packed in a large outer bag. When the milk is to be poured out, use scissors to cut a corner at the top bag corner, the handle and bracket fixed by the outside bag are poured into the jug. The use of LLDPE resin on the milk packaging bag not only provides strength for the milk bag, The pinhole property also allows the milk film to be heat-sealed and produced on the high-speed production line of the milk product factory, because DPE has a large thermal viscosity and can be heat-sealed even if the hot cover is contaminated.

The packaging of liquid dairy products includes the entire dairy product: low-fat, non-fat, flavored milk, cream, milk fat, egg packaging principle is www.handern.com hollow board equipment

① No leakage occurs in the packaging container that is resistant to breakage
② Ensure that no external impurities invade the content
③ There must be a method for easy removal of the product;
The frozen pot life of liquid pasteurized milk products is affected by the storage temperature, the degree of penetration of the packaging into the environment, and

① Both the product and its producer should be appraised. www.handern.com Hollow board equipment

The amount of natural bacteria present in the product is related, and the freezing pot life is about 14d. If the post-pasteurization treatment is anti-fouling, the long-term hollow board equipment is clean and sterile. The freezing pot life can reach 16 ~ 20d.
Month, it can only process and produce the so-called "ultra-high temperature milk" at a higher temperature. This milk is first pasteurized www.handern.com hollow board equipment
℃), then raise the temperature to a short period of 1 ~ 3s to kill the high temperature of bacteria, and then cool, quickly into the hollow plate equipment of www.handern.com
Vacuum chamber, when packaged in non-blocking containers, such as HDPE jars, the frozen shelf life of this type of packaged milk
