## 1. Executive Summary & Core Engineering Scope
Acrylic (PMMA), glass or PP for a face-cream jar: barrier, weight, formula compatibility, MOQ and lead time compared, and why every acrylic jar must be specified with a PP inner cup.

Three materials cover almost every cream jar on a shelf, and they are not interchangeable. Glass is inert and heavy, PP is robust and modest, acrylic is brilliant and must never touch the cream. This guide compares them on the things that decide a moisturiser programme — barrier, formula contact, weight, minimums and days — and explains the one rule that turns a good acrylic quote into a bad one.

For a face moisturiser, glass or PP may hold the cream directly; acrylic (PMMA) may not — oils and alcohol craze and cloud it, so every acrylic jar is specified with a PP inner cup , and an acrylic jar quoted "without liner" is a quote for a different product. Glass is inert with the best barrier at 2–3× the weight of plastic; PP is the standard for acids and oils and the cheapest route; acrylic gives the thick-wall, glass-look shell. Stock glass and PP both start at about 500 pieces , printed at about 2,000 ; glass runs 30–60 days , PP 7–25 days . Whatever the material, confirm it with the actual cream at 48°C for 30 days .

The choice is decided by what the cream does to the wall, what the wall does to the cream, and what the jar has to weigh and cost.

Acrylic is polymethyl methacrylate. Its virtues are optical — the highest clarity and gloss of the cosmetic plastics, and it can be moulded thick enough to give a jar the weight of glass at a fraction of the freight. Its weakness is chemical. PMMA has poor solvent resistance: oils, essential oils and alcohol attack the surface and the stressed regions of the moulding, and the damage shows as crazing (a network of fine cracks), clouding and, on a double-wall jar, a milky bloom where the cream has crept into the gap. Handbook practice is blunt about it: an acrylic jar generally cannot hold the bulk directly, needs an inner cup as a barrier, and must not be filled so full that cream reaches the space between cup and shell.

So the rule in every specification is the same: PMMA is the outer shell only; a PP (or PE) inner cup carries the cream; the fill line sits below the brim . The cup is a separate injection-moulded part with its own minimum, and it is the reason a lined 50 ml acrylic jar holds noticeably less than its outer size suggests — see why a 50 ml jar holds less than 50 ml . When a supplier quotes an acrylic jar "without liner" to hit a price, the cheaper number is for a jar that will fail the 48°C / 30-day test with any oil-rich or alcohol-bearing cream.
