Plastic Cap Or Aluminum Cap, which one is better
Plastic anti-thef caps is light and easy to open. Using it in the beverage
packaging, is not only convenient for consumers, but also speed up the
development of the beverage industry. Many enterprises has imported foreign
equipment, plastic cap began mass production and application. However,
aluminum cap is still widely used. Even some wine enterprises invested in 35%
of the cost in aluminum caps.

Previously, the main material of anti-thef caps is aluminum. But since the
mid-90s Coca-Cola used the Plastic cap instead of aluminum cap, Plastic Cap
has been pushed to the front of beverage packaging. Plastic cap or aluminum
cap, which one is better?
At present, the liquor, the wine and the medicinal liquor’s bottle cover are
mostly made with aluminum. This is because grass bottles are used in these
fields. By using hot forming process, there are large errors in the aperture
size. But using aluminum can achieve the relatively high seal. In the terms of
the raw material, the cost of aluminum is lower than the plastic (an aluminum
cap cost the half of an plastic cap), and anti-thef cap’s structure is very
complicated, the current production lines in wine industry are designed for
installing aluminum caps, if replaced by plastic caps, it will not only the cost of
raw materials, but also has a series of problems about change production

lines, bottle, cap re-design and so on. Therefore, companies are not willing to
cost energy and financial resources. What’s more, the aluminum anti-thef cap
is finished with high-quality aluminum alloy. It has superior performance, and
can be mechanized, mass production, and no pollution, and can achieve 100%
recycling, and also can meet special requirements such as high-temperature
steam sterilization. In addition, aluminum cap tend to replace the cork
because of the unnecessary of special open tool, and it has got many wine
companies favor.
Plastic cap can’t be close to the thermal forming grass bottle, so it’s
difficult to achieve a higher seal. As the plastic cap is easy to absorb the dust
in air, and the debris created when welding is difficult to eliminate, there is no
complete solutions to avoid the plastic debris and dust to pollute the wine.

Meanwhile, some plastic cap producers doped material which is not

Whether aluminum cap or plastic cap, each one has its own advantages
and disadvantages. Expert said that in a long period of time, aluminum is still
the preferred one in the anti-thef cap industry.
Since the mid 90s, Coca-Cola has produced PET bottled drink. They use
plastic cap replaced aluminum cap. Since then, plastic caps have been used in

drink industry more and more widely. The industry believes that technological
innovation has become a driving force for the rapid development of Plastic
Cap. And sometimes, the role of plastic in the bottle can not be replaced.
Because of a survey, people prefer the plastic cap with its strong security and
easy open process. Many businesses find that a small plastic cover is huge
market.
The expert said that the replacement of the bottle’s materials will bring
more choices of caps. Recently there have been two companies to develop a
suitable high-capacity high-density polyethylene plastic bottles of high sealing
screw cap. This cap can pull ring with plastic sealing film, consumers do not
rotate when the lid open, you can remove the cover, then pull the ring in the
bottleneck of the film, you can open the bottle. According to reports, this new
