Plastic Jars & Cream Pots

Wide-mouth jars for creams, scrubs and balms — single or double wall.

Plastic Jars & Cream Pots manufactured by SHIJIN
Overview

Engineered for your formula, finished for your brand

Jars are judged in the hand: wall weight, lid feel and liner seal. We mold single- and double-wall jars in PET, PP and PETG, with inner liners and tamper-evident options. Double-wall constructions give small formats a premium, heavy feel without glass cost or breakage.

Single wall, double wall and what the customer feels

The first decision on a cream jar is single wall or double wall, and it is as much a tactile decision as a cost one. Double wall gives the jar heft and a thick, premium feel, and it conveniently hides the fill-level shrinkage that a cream can show as it settles. Single wall is lighter, cheaper and perfectly respectable — but it is honest about the fill, which is not always what a brand wants.

Wall choice also drives decoration. A double-wall jar gives you a broad, uninterrupted surface for hot stamping or a wrap label, while a single-wall jar in a translucent colour lets the product itself read through the side. Neither is better; they sell different kinds of product.

Material follows the formula. PET and PETG give clarity and a glass-like presentation for premium creams and masks; PP and PE are the practical choices where chemical resistance matters or where the jar will be handled with wet hands. We will tell you when a formula rules a material out rather than letting you find out in month four.

Liners, seals and the closure nobody notices

A jar that seals is doing more work than it looks like it is doing. A PE foam or PET liner compresses against the jar mouth to guarantee the seal, and it is the reason a cream arrives without drying out or leaking into the carton. Tamper-evident bands and induction seals are available where the market or the channel requires them.

Closure feel matters more here than on a bottle, because a jar is opened and closed repeatedly over weeks. A cap that cross-threads, or one that needs two hands, is a complaint waiting to happen. We sample the assembled jar so you approve what the customer actually receives, not a jar and a lid that were specified separately.

For wide-mouth jars in particular, the mouth diameter and the thread have to suit how the product is used — a mask scooped with fingers wants a wider opening than a cream applied with a spatula. It sounds minor until the jar is in production.

Decoration, minimums and building a jar family

Jars are decorated in-house: silk screen, hot stamping for metallics, spray coating for frosted or gradient effects, and labelling for complex artwork. Because a jar presents a large flat lid, it is also the format where hot stamping earns its cost most obviously.

Minimums are 5,000 pcs for white, black and natural and 10,000 pcs for custom colours, and our 2,000+ mould library covers most common jar sizes from about 15 g to 300 g. If your line needs two or three sizes, running them in the same material and decoration language is what makes the range look designed.

Sampling on a stock tool is typically 3–10 days. If you want a shape that is genuinely yours, a private mould is quoted separately with a realistic timeline — and we will say so plainly if we think a stock jar with your decoration serves the launch better.

FAQ

Common questions about jars & cream pots

Single wall or double wall — which should I pick?+

Double wall reads premium and hides fill-level shrinkage; single wall is lighter and cheaper. For hot-fill or microwave-adjacent products choose PP, which is heat-resistant.

Do jars come with liners?+

Yes — PE foam or PET liners are standard for cream jars to guarantee seal. Tamper-evident and induction-seal options are available for food-adjacent products.

Which is better for a cream — a jar or a pump bottle?+

It depends on the formula and on how the customer uses it. A jar suits thick products that are scooped, and it lets the customer see and smell the product, which matters for masks and balms. A pump suits anything where hygiene or dose control matters, because the product is never touched. Airless pump bottles are worth considering for formulas with sensitive actives, since they reduce the air exposure that a repeatedly opened jar guarantees.

Will a plastic jar look cheap next to glass?+

Not if it is specified properly. The two things that make a plastic jar read as premium are wall thickness — which is where double-wall construction earns its cost — and the lid finish, where hot stamping or a soft-touch coating does most of the work. PETG in particular gives a heavy-walled clarity that most customers cannot distinguish from glass in the hand, at a fraction of the weight and breakage rate.

Do you supply the liners and seals as well?+

Yes. PE foam and PET liners are standard on our cream jars, and we can add tamper-evident bands or induction seals where the channel requires them. The important part is specifying the liner for the formula rather than defaulting to one — a liner that is fine for a water-based cream may not hold up against an oil-based balm, and that is a cheap decision to get right early and an annoying one to fix later.
