Call: Beer cap gaskets need to be upgraded for agents

Little crown caps are contacted almost every day, but little attention is paid. Metal crown caps ensure the sealing of beer and beverage bottles through the cooperation of iron sheet and sealing gaskets, and play an important role in the product quality and preservation of beer and beverages.

As a beer and beverage packaging supporting industry, China's metal crown cap industry continues to grow steadily and rapidly with the rapid growth of the Chinese beer and beverage industries. The production volume of the domestic leading beer bottle crown cap manufacturers also grows rapidly. In 2007, the production volume of domestic crown caps exceeded 60 billion. With an average of 350 mg of PVC gaskets per cap, the number of gasket pellets consumed as raw materials for polyvinyl chloride (PVC) exceeds 20,000 tons, making it the world's largest supplier of PVC gasket pellets. While cheering for the rapid growth of China's beer and beverage industry and the packaging and packaging industry, we also feel sorry to say that using such a large amount of PVC gasket materials is certainly not something to be proud of from the perspective of environmental protection and food safety. thing!

Persons engaged in the packaging industry know that foreign countries have begun to abandon PVC gasket materials as early as 20 years ago, and use non-PVC gasket particles. The main reasons are as follows:

1. Environmental Protection Organization pressure on the use of PVC. Polyvinyl chloride releases hydrochloric acid when it burns, causing acid rain. Only a burner equipped with a pickling device may remove all the hydrochloric acid emissions.

2. There is strong environmental evidence that uncontrolled PVC combustion produces high-intensity carcinogens such as dioxins.

3. Vinyl chloride monomer (VCM) is inevitably present as a cancerous substance in polyvinyl chloride, and its content in polyvinyl chloride has been greatly reduced to less than 1 ppm since VCM-to-cancer was discovered.

4. Plasticizers are precipitated into the food.

Phthalates and adipic acid, which are PVC spacer plasticizers, are all cancerous substances. (Europe has severely restricted or prohibited its precipitation, while absolutely prohibiting its use in alcoholic and fatty foods).

In summary, the non-PVC gasket material has these advantages of environmental protection and food safety, but it cannot be promoted in China for a long time. The reason is simple—who will bear the increase in cost.

For simple estimation, for bottle cap manufacturers, using non-PVC gasket materials to make caps, the cost per 100 million bottle caps is approximately 200,000 RMB higher than that of PVC gasket materials, and each bottle cap The cost rose by about 2%. In addition, due to the need to use non-PVC adhesive coating at the same time, non-PVC cap production process than PVC caps and other comprehensive factors, the total cost of non-PVC gasket caps is estimated to increase by 3% each, the cost increase of about 10% .

As China's Crown cap manufacturing industry generally obtains orders for beer and beverage factories through price competition, the profits are extremely thin. If beer and beverage manufacturers cannot increase purchase prices, Crown cap manufacturers can't take the initiative to lose money. Thinner gaskets produce crown caps. So far, more than 99% of China's crown caps are still PVC PVC gaskets.
