Two new products targeted to PET preforms, bottles and other PET packaging have been added by Ampacet to its portfolio of ScratchShield additive masterbatches that help to protect plastic products against scratch and abrasion without impacting gloss or mechanical properties of the resin.

The new ScratchShield masterbatch additives are said to minimize the appearance of scuffs and scratches in preforms, bottles and a range of PET packaging without the need to apply a surface coating. These additives are also said to significantly improve the demolding of preforms, while offering protection from guiderails and conveyor systems in the manufacturing process. The two ScratchShield products are also said to help reduce scrap, the need to regrind scratched bottles and cleanup associated with lubricant sprays.

Ampacet's new ScratchShield additive masterbatches for PET packaging

 ▪  ScratchShield PET 7000076-E, designed for blow molding processes, is a two-in-one solution providing antiscratch protection as well as slip properties for PET preforms and bottles. This additive restructures the surface of PET plastics, preventing crack propagation to limit whitening and hazing effects caused by abrasion. Ampacet ScratchShield PET 7000076-E also significantly decreases the coefficient of friction (COF) of PET during preform production, blow molding, handling and transport. This additive is said to significantly improves scratch and scuff resistance of preforms during conveyor belt handling.

 ▪  ScratchShield 7000109-N, for use in translucent color and opaque blow-molded bottles, reduces the occurrence and severity of scuffs and scratches at both the preform stage and in blown bottles eliminating the need for atomized sprays. In laboratory tests, ScratchShield dramatically reduced scuffs at load forces up to 100N (Newtons), and at forces lower than 25N scuffs were virtually eliminated in bottle-to-bottle scuff tests. Scuff visibility tests showed significant resistance to scuffing when PET bottles with ScratchShield were compared to PET bottles with no additives. ScratchShield 7000109-N is well-suited for applications such as alcoholic beverages (low alcohol), automotive products, cleaning products, lotions, juices and soft drinks, pet care products and water cooler bottles.

The new ScratchShield additives join existing products in the ScratchShield family to enhance PP, ABS, PET, PE, clear PS, and HDPE materials.
