TUZHE PACKAGING GUIDE
Clear Cake Box Materials: Component Specs and Use Conditions
Ask better questions about PET, recycled PET, PVC and PP packaging. Separate component identity, recycled-content claims and intended use from a clear appearance.

A clear cake box is a set of components, not necessarily one material. The wall, lid, base, coating and printed accessories may have different specifications. Start by identifying those parts before trying to choose from a list of resin abbreviations.
Request a component specification
Ask the supplier to identify the material used for each part of the proposed set. Record the component reference and any finish or layer that changes its construction. Do not infer the material of a base from the description of the transparent wall.
PET, PVC and PP labels identify material families; they do not, by themselves, describe the complete finished article. If the catalog uses a recycled-PET description, ask which component it refers to and what evidence supports the stated recycled content. Avoid extending a claim about one part to the whole pack.
Explain how the package will be used
Describe the food, the surfaces it may contact, the packing and storage conditions, and the intended duration of use. Explain whether a board or separate liner sits between the food and another component. Those details allow a supplier to answer a concrete question rather than a general request for “food-grade plastic.”
For U.S.-market context, the FDA explains food-contact substances in relation to their intended use. This is background for understanding the questions; it is not a claim that any Tuzhe catalog item has a particular authorization.
Keep recycled-content evidence separate
Ask what recycled-content statement is being made, which component it covers and how that statement is documented. Material identity, recycled content and suitability for an intended food-contact application are different questions.
The FDA recycled-plastics guidance discusses recycling-process information and proposed conditions of use. A favorable document for a particular process should not be treated as a blanket endorsement of every product made from recycled plastic. Have the relevant supplier documentation reviewed for the actual proposed construction and destination.
Use physical samples for the questions they can answer
A sample can show how panels connect, how the lid opens and whether a decoration clears the wall. It does not identify every material treatment or establish an unverified temperature or carrying limit. Keep observations about appearance and assembly separate from performance statements that need supporting evidence.
Compare round clear cake boxes described with PET lids or clear-panel frame boxes as structural references. Ask which parts of the selected set the stated material description covers. Use the round-cover loading check for the physical opening review.
Resolve the specification before writing the product claim
Your record should connect each component to its material description, intended use and supporting documents. Mark unanswered items explicitly. If a material or layer changes, revisit the associated statements instead of carrying old claims into new artwork.
The supplier evidence guide explains how to assess relevance and ownership of documents. Final supply and labeling decisions should be based on that specific record, not on how clear or glossy the photograph appears.
