Frosted glass splits into two engineering routes — chemical acid etching and laser frosting — that differ in the physics of material removal, the texture they leave behind, and the way they drift across batches. Glass is a recorded material and the recorded decoration register…

TL;DR Terpene-based formulations — botanical oils, fragrance concentrates, aromatherapy blends — stress polyolefin packaging two ways at once: the solvent wants to migrate through the wall, and chemically wetted plastic under load can crack. Fluorination of HDPE is the classic remedy, discussed here as treatment…

Fluted and ribbed glass is a molded-in decoration that reshapes the whole forming chain: mold relinquishment draft, wall distribution at rib crests, and thermal stress concentrations all behave differently when the cavity is no longer a smooth cylinder. Glass is a recorded material, and the…

Gel eyeliners dry out from the rim, not the middle: the pot is airtight only where the closure actually seals, and the solvents that keep the gel workable are exactly the ones a weak seal loses first. No gel-eyeliner pot model is recorded in the…

A magnetic compact is really two opening systems in one case: the magnet that snaps the lid home and the hinge that controls how that snap feels. The subject this month is the hinge's damping — the resistances that smooth the lid into a deliberate,…

A high-coverage foundation that stops delivering mid-bottle usually fails at the wet end of the pump: residual formula dries on the nozzle tip, film formers skin over exposed surfaces, and the elastomeric check element must reseal cleanly between strokes. This article anchors that problem in…

A swirl chamber is the atomization mechanism behind a fine spray on the actuator, fine-mist, and atomizer families — and in the catalog it is a project-level configuration, not a recorded field. This article anchors the discussion in the verified family frame — 42 actuator…

A dual-nozzle head on an airless pump turns a divided chamber into one coordinated dose: the two orifices sit apart, the phases blend in the bulk stream, and viscosity mismatch sets how wide the window can be. The record anchors the airless family at 89…

A low-profile collar compresses the dropper's neck into a flatter push-button head: travel distance decides how much air the button clears, an internal diaphragm reseal keeps the barrel airtight between draws, and dose linearity asks whether every stroke lands on the same target. The record…

Metal effects on caps and closures have one recorded route — electroplating — and vacuum metalizing is not a recorded decoration capability, so the process requires capability confirmation outside the published record before a project treats it as available, in the same discipline the program…

Compression blow forming (CBF) and injection stretch blow molding (ISBM) are two variants of one recorded capability, and both set the finish before the body is blown — which is why neck flash elimination belongs to the route itself rather than to a post-process trim.…

Bio-PET and virgin PET sound like one materials conversation, but in this program they sit on different sides of the register. PET is a registered bottle material, and the recycled-content PET variant is likewise recorded, with the recycled-content share defined per project — the entry…
