Packaging glossary

Plain definitions of the terms on our product pages — neck sizes, pump parts, closures, how the parts are made and how they are finished — each linked to the part it describes.

Neck sizes

Neck size (neck finish)

How a bottle neck is specified: two numbers, the diameter across the thread in millimeters and the thread style. Caps, pumps and bottles are all listed by this code. → Neck finish chart Ask about this one →

Reading 24/410

24/410 is a 24 mm neck with a 410 thread: the first number is the diameter across the thread, the second is the thread style. A cap fits when both numbers match the bottle. → Neck finish chart

DIN/ISO neck designations

The system many European buyers work to instead of the 24/410 style. Tell us which system you use and we’ll quote in that system. → Neck finish chart

Pump and sprayer parts

Dip tube

The tube a lotion or foam pump draws the product up through. Tell us the bottle height and we cut it to length. → Lotion pump Ask about this one →

Lotion pumps with their dip tubes

Piston (airless pump)

The disc at the bottom of an airless bottle that rises as the product is used, so there is no dip tube and air stays out. → Airless pump Ask about this one →

Dropper

A closure made of four parts: cap, collar, pipette and bulb — the closure on a serum bottle. → Dropper Ask about this one →

Droppers in silver, gold, white and black

Dose per stroke

How much a pump gives each time it is pressed: 2 cc or 4 cc on a lotion pump, about 1 cc on a cream pump. → Cream pump Ask about this one →

Closures

Child-resistant closure

A push-and-turn closure: you open it by pressing down and turning at the same time. Used for household chemicals and essential oils. → Child-resistant closure Ask about this one →

Child-resistant closure

Tamper-evident band

A band that shows the bottle has been opened before. It solves a different problem from a child-resistant closure; the two are often specified together. → Screw cap Ask about this one →

Liner

The insert inside a cap that seals against the rim of the bottle. Our screw caps come with the liner your product needs. → Screw cap Ask about this one →

How the parts are made

Extrusion blow moulding

A tube of melted plastic is closed inside a bottle-shaped cavity and blown out against its walls. It is how our HDPE bottles are made. → HDPE bottle Ask about this one →

Injection blow moulding

The plastic is injection-moulded onto a core rod as a preform, neck already finished; the core rod then carries it straight to the blow mould on the same machine, where it is blown into the bottle without being stretched. → Bottles & jars

Injection stretch blow moulding

A preform is stretched and blown into the bottle. It is how our PET bottles are made. → Bottles & jars Ask about this one →

Preform

The injection-moulded, test-tube-shaped piece, neck already finished, that a PET bottle is stretched and blown from. → Bottles & jars

Two-shot moulding

Two colors or two materials moulded into one part in a single tool, so there is no join that can come apart later. → Makeup packaging Ask about this one →

T1 / T2 samples

First samples (T1) come off the actual tool; if something needs adjusting, we correct it and send T2. Production starts only after you have approved a sample. → Design & tooling

Finishes, materials and files

Pad printing

Ink lifted by a silicone pad and laid onto the part. It follows a curved surface, which is why it is the usual way a logo gets onto a cap. → Custom & Private Label Ask about this one →

Silk screen

Ink pushed through a mesh. Denser and more solid than pad printing, on a flat or gently curved face. → Custom & Private Label

Hot stamping

Metallic foil pressed on with heat. The gold or silver band around a lid is usually this. → Custom & Private Label

Metallized

A mirror-bright metal layer on the plastic. It is what makes a cap read as metal on the shelf rather than as a painted part. → Custom & Private Label

UV coating

A clear coat cured under UV light. It is what stops a printed or metallized surface rubbing off in the carton. → Makeup packaging

Sleeving

A printed sleeve shrunk onto the body. It wraps the whole way round, so the artwork can run 360° around the body. → Custom & Private Label

Labeling

A printed label applied to the finished part. The quickest route when the artwork changes from one batch to the next. → Custom & Private Label

Moulded-in graduations

The dose marks on a dosing cap. They are cut into the tool, so they are moulded into the cap, not printed on it. → Dosing cap Ask about this one →

PCR

Post-consumer recycled plastic. We run PP, PE, PS and PCR blends; tell us the PCR share you need. → Bottles & jars Ask about this one →

PETG

The clear material of our double-wall jars. PETG resists impact, oils and actives. → Double-wall jar Ask about this one →

STEP / IGES

The file formats of the 3D model you receive, together with 2D drawings with dimensions. You check them against your own bottle and sign them off before steel is cut. → Design & tooling

    Questions

    What is a neck finish?

    The way a bottle neck is specified: two numbers, the diameter across the thread in millimeters and the thread style. 24/410 is a 24 mm neck with a 410 thread. Our caps, pumps and bottles are all listed by this code, and a cap fits when both numbers match the bottle. Not sure of yours? Send a photo.

    What is the difference between child-resistant and tamper-evident?

    A child-resistant closure opens only when you press down and turn at the same time, two actions that small children find hard to combine. A tamper-evident band shows that the bottle has been opened before; we put that band on our screw caps. They solve two different problems, and the two are often specified together.

    What is a T1 sample?

    T1 is the first round of samples off the actual tool. If something needs adjusting, we correct it and send T2. Before that, you see the 3D model (STEP / IGES) and 2D drawings, and production starts only after you have approved a sample.

    What is a dip tube?

    The tube a lotion or foam pump draws the product up through. We cut it to length from your bottle height, so tell us the height when you ask for a quote. An airless pump has no dip tube at all: a piston follows the product up the bottle instead, which keeps air out.
