pet preform Product developments in sparkling waters will direct bottle engineering projects towards barrier performance (CO2, O2, vitamins, natural flavourings) as opposed to light weighting initiatives, which will favour lighter weight monolayer solutions over heavier multilayer bottles.pet preform manufacturers household chemicals the trends are about inter-material competition. HDPE is the dominant polymer within this market. However, with the substantial reduction in price differential between polyolefins and PET, PET bottles continue to grow their market penetration.Colgate-Palmolive was the first to switch to PET and Procter & Gamble too has converted all dishwasher products (i.e. Fairy Liquid) and fabric conditioners to PET bottles in Europe, substituting HDPE. Other leading fillers in Germany have also converted.Yet within companies such as Unilever, Procter & Gamble, and Colgate-Palmolive, the balance of polymers is still broadly 75:25 in favour of HDPE versus PET. This presents a significant substitution opportunity for PET in applications and bottle sizes that don’t require a handle or are not subject to tight cost constraints. While growth prospects in general may be promising, the business remains challenging for raw material suppliers and converters alike in Europe. The forward focus for fillers is resource-efficient supply, driving the market toward on-site manufacturing options be it HTW (hole-through-the-wall), self manufacture, or blow moulding of preforms. This is limiting the ability of traditional converters to add value, while for European resin suppliers this is mainly a commodity business increasingly threatened by cheaper Asian and Middle East imports.
