Rigid plastic packaging is produced primarily from four resins: PET (polyethylene terephthalate), HDPE (high-density polyethylene), PP (polypropylene), and PS (polystyrene). PET dominates in clear bottles for beverages, cooking oils, and condiments — valued for its clarity, mechanical strength, barrier properties to oxygen and CO₂, and recyclability. HDPE is preferred for opaque bottles, jerry cans, and containers used with edible oils, household chemicals, and personal care products — offering good chemical resistance, excellent ESCR (environmental stress crack resistance), and food contact compliance. PP is the material of choice for snap-lid containers, food trays, and jars where clarity is less critical but temperature resistance is important (PP is microwave-safe, HDPE is not). PS (polystyrene) is used in clamshells and some food service containers but faces increasing regulatory pressure due to poor recyclability. Selection between these materials depends on the specific product, required shelf life, filling temperature, closure type, and destination market regulations. For EU markets, the PPWR (Packaging and Packaging Waste Regulation) is introducing recyclability requirements and recycled content mandates for plastic packaging — rPET and rHDPE certified recycled-content packaging is increasingly demanded by major retailers.
Neck finish standards and closure compatibility
Neck finish compatibility between bottle and cap is critical — the thread profile, diameter, and pitch must match the closure. The most common international neck finish standards for plastic bottles in food and beverage applications are PCO 1881 (the global standard for carbonated soft drink and water bottles — used with 28mm diameter closures), 28mm 1881 neck (same diameter as PCO 1881 but different thread profile — common for still water and juice), 38mm neck (common for cooking oil and condiment bottles), and BPF (British Pharmaceutical standard, widely used for household liquids). For cooking-oil bottles, the 38mm or 28mm neck with an appropriate dispensing closure or screw cap is most common. When sourcing bottles and closures from different suppliers, always request the specific neck finish standard code from the bottle supplier and confirm it matches the closure supplier's compatibility list before ordering tooling or production stock. Proprietary neck finishes require matching proprietary closures — avoid these unless your filling line is already tooled for them.
Frequently asked questions
What is the difference between injection moulding and blow moulding for plastic packaging?
Injection moulding fills a closed mould with molten plastic under pressure — used for solid or near-solid items (caps, closures, lids, jars, trays, crates). Extrusion blow moulding extrudes a tube of molten plastic (parison) and then inflates it inside a mould — used for HDPE bottles, jerry cans, and large containers. Stretch blow moulding starts with an injection-moulded PET preform, reheats it, and stretches it axially before blowing — used for clear PET bottles and achieves better clarity and barrier properties than extrusion blow moulding. When sourcing, clarify which process your supplier uses for the specific product and confirm that the process is appropriate for your application.
What food contact certifications should rigid plastic packaging carry?
All rigid plastic packaging in direct food contact must comply with EU Regulation 10/2011 (plastic food contact materials) for the EU market — the supplier must provide a Declaration of Compliance (DoC) confirming the specific resin grade and colourant comply with the regulation's positive lists and overall and specific migration limits. For the US market, FDA 21 CFR Part 177 compliance documentation is required. For UK markets post-Brexit, the equivalent UK Food Contact Materials Regulation applies. Additionally, BPA-free certification should be requested for PC or epoxy-coated packaging; phthalate-free confirmation for soft PVC items. Any recycled-content plastic used in food packaging must come from a food-grade approved recycling process (typically EFSA-approved for EU market).
What is rPET and why is it increasingly required for plastic bottles?
rPET is recycled polyethylene terephthalate — PET plastic recovered from post-consumer waste (primarily drinks bottles) that has been cleaned, decontaminated, and reprocessed into pellets suitable for bottle manufacturing. EU Regulation 2025/40 on single-use plastics requires a minimum of 25% recycled content in PET beverage bottles from 2025, rising to 30% from 2030. The broader PPWR (Packaging and Packaging Waste Regulation) introduces recycled content requirements across more plastic packaging categories from 2030. Major food and beverage brand owners are also setting voluntary recycled content targets ahead of regulatory deadlines. When sourcing PET bottles with recycled content claims, require Global Recycled Standard (GRS) certification from the supplier — GRS provides third-party verification of recycled content percentage and supply chain traceability.
