China's custom Plastic Bottle packaging era began to come
Because the flexible packaging of Plastic Bottles to meet the requirements of diversification of goods, significantly improve the shelf life of food; and packaging process is simple, easy operation and use; with the affinity of the packaging; saving packaging costs and transportation costs; low energy consumption, environmental protection and other advantages The So flexible packaging of Plastic Bottles in many areas play an increasingly important role.
It is understood that with China's Plastic Bottle flexible packaging industry supply capacity of the continuous improvement of the export growth of products will provide more opportunities, in addition, with the domestic consumer market continues to mature will make the export market into more enterprises to seek sustainable An important way to develop. In short, China's Plastic Bottle flexible packaging industry, the export market prospects will be very broad.
At present, China's beverage consumption continues to rise, providing significant growth for beverage packaging manufacturers. It is predicted that in 2017 the global beverage packaging market value will reach 118.8 billion US dollars. Such a broad market prospects, determines the beverage packaging must be constantly in the technical innovation, in order to follow the pace of development of the beverage.
Most of the beverage manufacturers are only concerned about the economic benefits, while the Plastic Bottle crafts rarely from the ecological point of view. More diverse products, require more differentiated packaging, has become the development trend of the beverage industry, beverage packaging machinery technology development will become the ultimate driving force of this trend.
The next three to five years of the beverage market in the development of the existing juice, tea, bottled drinking water, functional drinks, and carbonated drinks and other products at the same time, Plastic Bottles will be low-sugar or sugar-free drinks, as well as natural, Including milk and other health drinks direction. The development trend of the product will further promote the development of different packaging, such as PET aseptic cold filling packaging, HDPE milk packaging, and sterile carton packaging.
Although the green packaging is not yet a fully defined definition, but in general, can be reused, recycled or degraded corruption, and in the product throughout the life cycle of the human body and the environment does not cause moderate pollution, called green package.
The most important meaning of green packaging is to protect the environment, but also both the significance of renewable resources. Green packaging in its entire life cycle process, follow the circular economy "reduction, re-use, resource-based" economic activities of the principle of behavior, so that the impact of packaging on the environment to a minimum.
China's flexible packaging industry in the original heavy wind, adhere to the fundamental, more energy-saving energy, energy consumption, emission reduction, Enron, is to stay modified Plastic Bottle of God to enhance the skills, for BOPP Plastic Bottle film easy to infect the title of the problem.
Plastic Bottles in the flexible development of flexible packaging at the same time, Plastic Bottles and flexible packaging enterprises should focus on the Plastic Bottle packaging on the security issues. So that the Plastic Bottle flexible packaging industry can be developed by leaps and bounds.
(1) When designing extruded Plastic Bottles, if the material is made of high density polyethylene or polypropylene, the cross section of the Plastic Bottle should be rectangular or oval. For materials with low density polyethylene or other flexible Plastic Bottles, The cross section is rounded as well. This facilitates the extrusion of the contents from the Plastic Bottle. Plastic Bottles used in conjunction with Plastic Bottles are mainly caps and sealers. The design of the Plastic Bottle should focus on the test; how to make the Plastic Bottle can be better with the lid and seal with the bottom of the Plastic Bottle, Plastic Bottle is a weak mechanical properties. Therefore, the bottom of the Plastic Bottle is generally designed into the concave; Plastic Bottle corner, and the concave, are doing a larger arc over. In order to facilitate the stacking of Plastic Bottles, increase the stability of the Plastic Bottle stacking, Plastic Bottles should be designed at the bottom of the groove.
(2) Plastic Bottle surface with labels, the standard surface should be flat. Can be designed in the Plastic Bottle surface of a "grid", so that accurate positioning of the label, does not produce mobile. In the blow molding, the billet inflation first contact with the site, always tend to harden the site. So the wall thickness of the site is also larger. Edge and corner parts, is the last part of the parison inflation contact, the site of the wall thickness is small. So the edge of the Plastic Bottle and the horn parts should be designed rounded. Change the surface shape of the Plastic Bottle, such as the middle of the Plastic Bottle is relatively thin, increase the surface of the Plastic Bottle groove or ribs, can improve the Plastic Bottle stiffness and bending resistance. Longitudinal grooves or ribs can eliminate the offset, sag or deformation of Plastic Bottles under long term loads.
