Frequently Asked Questions
What neck finishes are available for PET preforms?
iBottling supplies PET preforms in PCO 1810 (standard water/CSD up to 1.5 L), PCO 1881 (carbonated up to 2 L), PCO 1881 HS (hot-fill), 29/25, 38mm tamper-evident, 26mm, and custom dimensions. Neck finish selection is matched to your capping machine and bottle design.
What preform weight is recommended for my bottle size?
As a general guide: 330 mL bottles use 12g–16g preforms, 500 mL uses 18g–24g, 1 L uses 28g–36g, and 1.5–2 L uses 32g–42g. Final weight depends on bottle geometry, carbonation pressure, and wall thickness requirements. Our team recommends the optimal weight during specification review.
Are PET preforms compatible with iBottling blow molding machines?
Yes — all three preform types have been reviewed for compatibility with iBottling blow molding equipment. Crystal preforms work with most iBottling models including semi-auto machines. Heat-set preforms require machines with extended cooling zones. Lightweight preforms are designed for high-speed automatic machines with thin-wall capability.
What is the minimum order quantity and lead time?
Standard MOQ is 50,000 pieces per SKU. Lead time is 15–25 working days ex-works. Custom colours, printing, or special barrier materials may require higher MOQ and extended lead time. Pallet packing is arranged by weight: 1,000–4,000 pcs per pallet.
Can preforms be supplied as part of a complete bottling line package?
Yes. PET preforms are included in turnkey bottling projects alongside blow molding machines, fillers, cappers, beverage labels, and shrink film. This ensures preform neck finish matches capper configuration, weight matches blow molder cavity design, and material grade matches beverage type — one procurement package with full compatibility verification.
