How should I specify roll width, roll diameter and core size when ordering thermoforming sheet?

Roll dimensions should match the customer's thermoforming and feeding equipment. Roll width is normally determined by mold layout, product arrangement and trim allowance, while rol…

What should I consider when selecting clear sheet for thermoformed packaging?

Clear sheet should not be selected by transparency alone. Buyers should consider the required clarity together with stiffness, forming depth, impact performance, temperature condit…

How should I specify thermoforming sheet for a food tray instead of simply asking for “food-grade sheet”?

“Food grade” alone does not define a usable thermoforming specification. Buyers should also identify the food type, tray dimensions, forming depth, storage temperature, transparenc…

How should I select plastic sheet for deep-draw thermoforming?

For deep-draw parts, nominal sheet thickness alone is not enough. The main concern is how the material distributes from the flange and sidewalls to the deepest area during forming.…

What information should I provide to select the right plastic sheet for a new thermoforming project?

For a new thermoforming project, the sheet should be selected from the finished part backward. Start with the application, material requirements, part dimensions, forming depth, re…

What information should I provide when requesting a quotation for custom thermoforming sheet?

A useful quotation request should include more than “PET/PP/PS sheet price.” Buyers should provide material, thickness, width, color, transparency, roll dimensions or core requirem…

Why does plastic sheet curl or become difficult to feed before thermoforming?

Sheet curl can be related to material structure, residual stress, winding, storage conditions, temperature changes or moisture and handling conditions. The cause should be separate…

What should buyers confirm when sourcing plastic sheet for medical or pharmaceutical thermoforming packaging?

Medical and pharmaceutical packaging requirements vary greatly by application. Buyers should first define whether the sheet is used for a protective tray, device packaging, pharmac…

When does electronics packaging require anti-static or ESD thermoforming sheet?

Not every electronics package requires anti-static or ESD material. The requirement depends on the sensitivity of the component and the customer's electrostatic-control system. Sta…

How do I determine the right thickness and width for thermoforming sheet rolls?

The correct specification should be based on the finished part and production equipment. Thickness depends on material, forming depth, part dimensions, stiffness and final thicknes…

How should I select thermoforming sheet for cups, cup lids and dairy containers?

Cup and dairy packaging requires attention to more than sheet thickness. Material selection should consider cup depth, rim geometry, stacking, filling temperature, sealing method, …

What should I consider when choosing sheet for refrigerated food and fresh meat trays?

Refrigerated packaging requires more than good room-temperature forming performance. Buyers should consider low-temperature behavior, tray rigidity, impact resistance, condensation…

What should buyers consider when selecting plastic sheet for thermoformed food packaging?

Food packaging sheet should be selected according to the food type, storage temperature, package structure, forming depth, sealing method and destination-market compliance requirem…

Why does PET sheet crack, whiten or form poorly during thermoforming?

PET thermoforming problems are not always caused by the sheet itself. Cracking, whitening and poor forming can result from unsuitable heating, uneven sheet temperature, excessive f…

How do I choose between PET, PP and PS sheet for thermoforming?

Choose the material according to the finished package rather than price alone. PET is commonly selected when transparency, stiffness and product visibility are priorities. PP is of…
