Thermoforming

A forming process in which heated plastic sheet is stretched over or into a mold.

Thermoplastics

Plastics that can be reheated and reshaped after initial forming. Their reversibility is one reason they dominate manufacturing.

Thermosets

Plastics that cure into a permanent shape and cannot simply be remelted and reformed. Once set, they are committed in a way thermoplastics are not.

Thick Wall

A container construction using extra wall thickness for strength, feel, or premium appearance.

Thread Finish

The thread design and dimensions on a container neck that determine closure fit.

Thread Pitch

The distance between adjacent threads on a finish or closure. It influences how quickly the cap advances and how the sealing action behaves.

Thread Turns

The number of rotations required to fully apply or remove a threaded closure.

Tight-Head

A drum with a sealed, non-removable top and dedicated openings for filling and dispensing. It is chosen when strength and containment matter more than internal access.

Top Gate Lid

A lid with an opening or access point located at the top center area. It directs the user toward a particular mode of dispensing rather than a full opening.

Tote

A large reusable container used for bulk handling and transport.

Tray

A shallow open container used to hold, separate, display, or support products.

Trigger Sprayer

A spray device operated by a lever-style trigger.

Triple thread

A thread configuration with multiple thread starts that allows faster closure application.

Tub

A wide, open-top container often used for foods, creams, or larger-volume products. NOT the kind to take a bath in.

Tube

A flexible cylindrical package used for creams, gels, pastes, and similar products. Tubes are designed around controlled squeezing.

Tuscany Jar

A decorative jar style with rounded, classic lines often associated with premium presentation.

Twin-Neck Bottle

A bottle with two separate neck openings. It is uncommon, and for that reason usually tied to a very particular dispensing or formulation purpose.

Twist-Open Dispensing Lid

A dispensing lid that opens or unlocks through twisting motion.

U

Ullage

The empty headspace left in a package after filling.

UN Rated

Packaging certified to meet United Nations performance standards for transporting hazardous materials.

Uncontrolled Dropper Tip

A dispensing insert that allows liquid to flow out without strong metering or drop-by-drop control.

Unit Load

A group of products handled as a single transport unit.

Up-Lock

A pump feature that locks by lifting or twisting into an upper secured position. It prevents accidental actuation and keeps the product where it belongs.

Urea

In packaging, this refers primarily to urea-formaldehyde resin, a thermoset material used to produce rigid closures.

UV Coating

A surface coating cured instantly or rapidly with ultraviolet light.

UV Protection

The ability of a package or material to shield contents from ultraviolet radiation.

V

Vacuum Packaging

A packaging method where air is removed before sealing to extend shelf life or reduce oxidation.

Valve Closure

A closure that incorporates a valve to regulate flow, venting, or one-way movement.

Varnish Coating

A clear or tinted protective coating applied over printed surfaces.

Vector

Artwork defined by mathematical paths rather than a fixed grid of pixels. Vector graphics scale beautifully, which makes them the grown-up choice for logos and line work.
