plastic clamshell packaging

Plastic Clamshell Packaging Sourcing helps US packaging buyers start a factory brief for a thermoformed hinged pack. Name cavity size in mm, wall thickness in mil or μm, quantity unit and destination so original-manufacturer wholesale quotes can share one specification. Directory names are not warehouse stock.

Material

PET, RPET, PP or HDPE and any post-consumer recycled content claim tied to a batch file

Size

Cavity length, width and depth plus wall thickness in mil or μm

Print

Flexographic printing, digital print or gravure printing colors and die line status

Quantity

Pieces or cartons and the ship-to state or postal code

Empty PET clamshells on an inspection bench with a cavity gauge — Inspection-bench sketch for a measured plastic clamshell packaging brief. Not a factory identity, filled inventory or completed project.

What belongs on the first procurement brief

Measured product form

Start with plastic clamshell packaging as the family, then name a hinged tray, berry box, bakery shell or a bottle-and-jar companion SKU so factories quote the same blank.
Cavity, gauge and hinge lock

Write cavity millimetres and wall thickness. A snap lock is not interchangeable with a button lock or a tamper tab without a new tool insert.
Quantity unit and destination

State pieces or cartons and the US state or postal code. Freight, nested sleeves and inner cartons stay outside the piece price unless the plant writes them in.
Documents to request later

Food-contact statements and migration testing files belong to a named resin and ink pairing. This desk does not display site-wide FDA or BRCGS badges.

ISO ICS 55.020 supplies packaging-unit vocabulary for this page. Packhelp quote and wholesale pages, accessed 2026-09-15, are used only as a brief-first process reference, not as this site's factory network or lead time. Ahrefs US matching-term labels recorded 2026-08-25 (Image pack, Shopping, People also ask) inform page intent; they are not rankings.

Read the RFQ checklist article before sending the form, then open the inquiry options.

Buyer settings that change the RFQ

Produce clamshells staged for a retail pack

Produce and berries

Vent holes and hinge stiffness change both the tool quote and the carton nest height.

Bakery and deli

Anti-fog PET and a deep cavity need their own gauge line if they are not part of the tray quote.

Electronics kits

Static-sensitive parts often specify a carbon-loaded wall; still write cavity count and lock force.

Personal-care kits

Incoming quality often asks for a die line and a migration testing file before a line trial.

Device trays

Small cavities still need a named lock style and a pallet pattern that survives parcel sort.

Contract packing

Line-trial timing, artwork freeze and sample path belong on the brief even when the filler is a third party.
