Frequently Asked Questions
What should be checked before approving a custom pinch lock tray sample?
Buyers should check product size, product weight, tray length, tray width, tray depth, side wall height, paperboard GSM, paperboard caliper, tab size, slot width, lock tolerance, crease depth, insert requirement, insert height, sleeve clearance, clear lid fit, product loading direction, inside printing, outside printing, barcode or QR code position, surface finish, material requirements, flat-packed quantity, carton packing method, and destination country.
Does a pinch lock tray need glue?
No. A pinch lock tray is designed for glueless manual assembly.
What is the difference between a pinch lock tray and a simplex tray?
A pinch lock tray usually has single-wall side panels, which makes it lighter and more material-efficient.
What products are custom pinch lock trays best for?
Custom pinch lock trays are best for lightweight to medium-weight products such as cosmetics, nail polish sets, skincare samples, medical vials, ampoules, stationery, pens, small accessories, gift sets, and promotional kits.
What products are not suitable for pinch lock trays?
Pinch lock trays are usually not suitable for heavy glass jars, large candles, metal parts, sharp products without insert protection, products requiring high stacking strength, or rough e-commerce shipping without an outer carton.
How much weight can a pinch lock tray hold?
The suitable load depends on tray size, tray depth, side wall height, product weight, paperboard thickness, tab size, slot width, insert support, and handling method.
How tight should the locking tabs be?
The tabs should be tight enough to hold the side walls, but not so tight that workers must force the tray together or tear the tabs.
How do I choose the right paperboard GSM and caliper?
Paperboard GSM and caliper should be selected based on product weight, tray depth, tab size, slot width, crease depth, and surface finishing.
Can pinch lock trays be paired with sleeves, clear lids, or inserts?
Yes. Pinch lock trays are often paired with printed paper sleeves, clear PET lids, paperboard inserts, EVA foam inserts, molded pulp inserts, or mixed-material inserts.
How should sleeve clearance be tested?
Sleeve clearance should be tested with the finished tray, insert, and product inside, not only with a flat dieline.
Can pinch lock trays be used for cosmetics, food, or medical vials?
Yes, they can be used as secondary packaging or presentation trays for cosmetics, food samples, medical vials, or ampoules when the material requirement is reviewed properly.
Can I print inside the tray?
Yes. Inside printing can be used for branding, instructions, QR codes, product placement guides, color blocks, or welcome messages.
How are pinch lock trays packed for export?
Pinch lock trays are usually packed flat to reduce storage volume and shipping cost.
Can FSC-related paper and material documents be checked?
Documentation or certification scope must be confirmed for the selected material, supplier, production route, intended use and destination.
What information do you need for a quote?
Please send your product size, product weight, tray depth, sleeve or lid requirement, insert need, artwork file, quantity, packing method, and delivery country.
