Analysis of the application advantages of PET bottle beer packaging

With the continuous improvement of PET bottle making technology, the application of PET bottles in beer packaging has also developed rapidly. PET bottles have the following advantages over traditional glass bottles.

1. High security

Beer is a low-alcohol beverage with high CO2 content. It must be pasteurized after high temperature. This process will cause CO2 to swell and lead to increased pressure inside the bottle. Therefore, the glass bottled beer sold in the market is belt. The pressure product, in addition to the glass bottle itself is cumbersome and brittle, if handled improperly during transportation, handling, storage and opening, it will cause a bottle explosion. According to incomplete statistics, the annual incident of beer bottle explosions in China is as high as possible.

6000. The PET bottle has the characteristics of light weight, impact resistance and non-breaking. It is obviously superior to the glass bottle in safety, and will not cause personal injury to the production line staff and consumers, and avoid unnecessary loss.

2. Easy to carry

The PET bottle is easy to carry, and has greater flexibility in bottle type and capacity selection. It can produce different bottle types and different capacity products according to different market demands, which can not only enrich beer products, enhance brand image, and enhance market competitiveness. It can also meet the needs of specific consumer places and people. Especially in today's society, car consumption has stimulated people's consumption habits to create new demands, such as the increase in activities such as suburban activities, family gatherings, sports tourism, etc., which has also promoted the emergence of more beer packaging forms, especially large capacity ( 1.5L, 2.5L, etc.) beer packaging, and this is precisely the "short board" of glass bottles.

3. Health and environmental protection

At present, the PET bottled beer production line widely uses the method of connecting the blowing machine and the filling machine, which not only eliminates the bottle washing process of the glass bottle, but also effectively reduces the risk of microbial contamination of the empty bottle during storage, and ensures the irrigation. The sanitation and safety of the installed environment, as well as the reduction of bottle washing water and bottle washing agent, avoiding the discharge of waste water and energy consumption after washing the bottle, and reducing the intermediate links of the transportation and the bottle of the glass bottle, and reducing the resources to some extent. Consumption, in line with current green environmental requirements. In addition, the high recycling rate of PET bottles is conducive to environmental protection and efficient use of resources.

4. Easy to transport

The glass bottle is brittle and fragile, and has low mechanical strength. During transportation, special protective packaging needs to be installed to avoid damage or even bottle explosion caused by collision between bottles due to vibration shock during transportation. Moreover, the height of the stacking of the glass bottles during storage should not be too high, generally not more than 5 bottles. The PET bottle is light in weight, and the PET bottle with a capacity of 0.5L is only 24 to 40g, and does not require special transportation protection, which is convenient for long-distance transportation. At the same time, the outer packaging of PET bottled beer can be wrapped with plastic film, which is more traditional than corrugated box and plastic.

The material turnover box should be light and convenient, and the product display effect is good, the packaging cost is low, it is not easy to be damaged by moisture, and the storage cost can be greatly reduced. (Editor: Wang Yang)
