Dutch company Holland Colours has developed a new generation slip agent, which can reduce scuff marks and scratches on PET packaging.
Called as HolcoSlip, the slip agent lowers the coefficient of friction (COF) of PET during preform production.
Lowering the COF leads to an easier release of the preforms from the cavities, creating scratch-free preforms due to less friction and reduced marks from performs falling into the octabin, which is an octagonal corrugated bulk box.
For several years, Holland Colours has been supplying colourants and additives for the PET packaging market.
The company stated: "Our latest developed new generation slip agent (HolcoSlip 271-Series) expands the portfolio to provide our customers with more efficient and cost-effective solutions."
The company claimed that 10% more preforms can be stored into an octabin, reducing storage and transportation costs.
Compatible with most liquid additive/colourant dosing systems, the slip additive can also be used at a significantly lower dosing level, about 50% lower, to get the same effect as most other competitive solutions in the market.
Other advantages offered by the slip agent are that it is bio-based and claimed to be environmentally and food contact safe, has negligible influence on the PET-conversion process, offers no discoloration, and preforms are more easily ejected from the core of the mould.
