Global migration values in water (mg/dm2) < 3Ĭomponents susceptible to specific migration: Barium, Cobalt, Copper, Iron, Lithium, Manganese, Zinc, Aluminium and Antimony. Regulation (EU) No 2019/37 of 10 January 2019, which alters or amends Regulation (EU) No 10/2011 for plastic materials and articles in contact with water.Commission Regulation (EC) No 2023/2006 of 22 December 2006 on good manufacturing practice for materials and articles intended to come into contact with food.Regulation (EC) No 1935/2004 of the European Parliament of 27 October 2004 on materials and articles intended to come into contact with food and with the provisions of Article 5 of the quality assurance system.The product complies with the requirements of the standard(s) and regulation(s): The PET Preform 460gr is available in Blue. Includes neck ring for better attachment of the hanging handle. The colors in which it is manufactured provide protection to the water against the solar rays UV, and at the same time we obtain the final aesthetic of the bottle. The raw material of the 460gr PET Preform is guaranteed by the Hods Quality Assurance. Recommended for the manufacture of 12 litre bottles. Joint us to discuss and select neck finish for your bottle.Description PET Preform 460gr BISPHENOL-A FREE. Some of these materials are polyvinyl chloride or PVC, polyethylene or PE, polyethylene terephthalate or PET, etc. Different types of materials are used to make plastic bottles. Many of the bottles are made from PET preform. More preform neck designs for different applications are available in the market. The Preform is an intermediate product that Preform can convert into a variety of bottles. Remember savings on both preforms and caps (or closures) by selecting right necks! Compare neck designs below may assist your choices. Neck design is also important to reduce cost as well as to save non-renewable resources. Welcome viewers to send us comments for improving preform design. For the preforms of wide neck jars, however, the possibility of processing seems more important than the stretch ratio when we design preforms. * Above data is obtained from our experiences and observations and it is for reference only for designing most drink bottles with narrow neck finishes. W is the wall thickness of bottle, w is the wall thickness of preform. L is bottle height excluding neck, l is preform length excluding neck.ĭ is bottle diameter, d is preform diameter. R is biaxial stretch ratio, X and Y stands for stretch ratio of each direction. Length of the preform will be around 300/2.83=106mm, (l = L / Y) ĭiameter of the preform will be around 95/2.83=33.5mm, (d = D / X). Wall thickness of the preform will be around 0.5x8=4mm, (w = W x R) The preform wall thickness is bottle wall thickness times biaxial stretch ratioįor example, if the desired bottle wall thickness is 0.5mm, height is 300mm excluding neck, diameter is 95mm The preform diameter is the bottle diameter divided by 2.83 (d = D / X) Preform length can be decided based on bottle height (minus neck where no stretch is made) divided by 2.83 (l = L / Y) The Desirable Biaxial Stretch Ratio is around 8Įach direction of X and Y stretch ratio is about 2.83 (R = X x Y) How to optimize preform design and minimize PET resin consumption is always challenging to every bottle maker to obtain quality PET bottles.
