Paperlike Masterbatch consists of a concentrated mixture of pigments and/or encapsulated additives manufactured by heating a carrier resin and then cooling it and cutting it into granules. The masterbatch thus allows the transformer to colour and give characteristics to the natural polymer economically in the plastics transformation process.
The masterbatch carrier must be identical/compatible with the polymer. For example, EVA or LDPE is a compatible carrier with polyolefins and nylon, as is polystyrene with ABS, SAN and sometimes polycarbonates.
In this sense, when the masterbatch carrier is incompatible with the raw material, changes may occur in the properties of the processed material. The processor must specify the characteristics of the raw material. The percentage of use of masterbatches in relation to the raw material is between 1 and 5 %. Colour and additive masterbatches can be combined.
Masterbatches are compatible with most processes, with the exception of rotational moulding, plastisol and other liquid resin systems.
This multi-component system of specialty additives and minerals provides a cost-effective solution for synthetic film applications. Papermatch masterbatch imparts to film paper-like feel, qualities and printability, including increased stiffness and maximum deadfold properties. Papermatch masterbatch can be used in blown or cast film applications. Its available in both pigmented and natural tones, in a variety of finishes from very smooth to very coarse, and is FDA approved.
Applications include banners, book covers, maps, labels, standup pouches, courier envelopes, lumber wrap and house wrap.
