Sample text

The stretched preform is trimmed to provide the correct length and is then flanged and reformed into a can body. The open top can body is now trimmed to a precise length in preparation to neck-in and flange to the correct diameter to take a seamed metal end (209 diameter). The finished can is a 12 oz oriented PET necked-in beverage can with a draw wall ironed (DWI) base. The first commercial scale production lines using modules produced by Krupp Corpoplast were installed in the Petainer plant in Atlanta, US, and the first Petainer cans were produced in 1986.

Another factor to consider is the impact of UV light. As the beer sector for PET bottles grows, it will be mainly in the single-serve market and UV will play a major part on the resultant shelf-life. This will require developments in UV light barriers (in the 350-450 nm wavelength band), therefore we see mainly amber coloured PET bottles for beer. In Japan, however, all coloured PET will be eliminated from I April 2002! Thus, we will see developments in the area of increasing UV barrier for clear PET containers in the coming years.

This will further increase the switch from glass and metal cans. The perceived quality of products packed in glass compared to those packed in PET has narrowed, and in some markets PET has overtaken glass. This will further facilitate the conversion to PET and will be worth serious consideration when assessing future packaging needs for packer/fillers and brand owners. PET has become the material of choice for so many markets that it will continue to go from strength to strength for many years to come.
