Plastic jars are wide-mouth containers produced by injection stretch blow moulding (PET) or injection moulding (PP, HDPE, PET) — distinguished from bottles by a mouth diameter typically more than 45mm, enabling easy access for filling, scooping, and product removal. The primary materials are PP (polypropylene) — opaque or semi-translucent, microwave-safe, dishwasher-safe, chemical-resistant, the standard for food storage jars, cosmetic jars, and supplement containers; PET — clear, lighter than glass, good barrier properties, the preferred choice where product visibility is required (salsa, relish, nut butters, honey, jam); and HDPE — opaque, excellent chemical resistance, suitable for household and industrial applications. Lid and closure types for plastic jars include: press-on slip lids (the simplest format for internal storage and industrial containers), screw-on lids (threaded neck, the standard for food and cosmetics retail jars), lug caps (standard for food jars processed by pasteurisation or retort — the lug provides audible click feedback confirming the vacuum seal), and induction-seal liner caps (where an aluminium foil induction seal provides tamper evidence and additional barrier for food, pharma, and cosmetics). When sourcing for food applications, confirm food-grade compliance: PP under EU Regulation 10/2011 or FDA 21 CFR 177.1520, PET under EU 10/2011, and request the manufacturer's Declaration of Compliance.
