With the rising prices of energy materials and the increasing attention to environmental pollution issues, enterprises' direction also needs to be adjusted again and again to keep pace with the times. The rubber and plastics industry uses recycled materials and the lightweight design is the development trend of the industry. The lightweight plastic bottle has the benefits on resources, the environment and the profitability of enterprises by showing goodwill in the environment, companies can also save costs. So how can we achieve the purpose of lightweight plastic bottles?

Start from the two aspects of self-weight reduction of plastic bottles, one is to reduce the weight of the bottle mouth, and the other is to reduce the weight of the preform (bottle body). At present, to reduce the weight of the bottle mouth, you can refer to the "short bottle mouth" series of the International Association of Beverage Technologists, such as: PCO1881 or 29/25. Reducing the weight of the bottle mouth not only reduces the weight of the bottle itself, but also reduces the weight of the corresponding plastic cap, so as to achieve the purpose of double saving materials and costs.

The weight of the preform is reduced, which also means the weight of the bottle body is reduced. It needs to be promoted by multiple aspects, such as the design of the preform, the bottle, and the mold. Relatively speaking, the physical debugging of materials, the improvement of blowing technology...etc. It takes a large group of people to work for many years to reduce 1g. At present, the technology of bottle weight reduction is not popular and is unique to each manufacturer. The price is high and the maturity is not enough. It is expected that there will be a general technology in time, which will take a big step for the lightweight of the plastic bottle market.

The research and development of lightweight technology still needs continuous efforts, the unstoppable pace of the times, and the continuous overthrow and explosion of technology allow people to maintain the convenience of life and protect the living environment at the same time.
