Selection and sampling
Confirm item by item, from intended use to sample
- 01Describe the intended use
Explain the downstream processing, packaged object, and use context.
- 02Check the parameters
Organize dimensions, form, color, surface, and quantity conditions.
- 03Confirm with a sample
When needed, use a sample to check appearance and downstream processing performance.
- 04Agree on acceptance
In later discussions, specify batch documents and acceptance items.
Information needed for a quote
Please provide the material, intended use, quantity, dimensions, color, surface requirements, delivery location, and preferred reply time. You may also state that the material is not yet decided.
Go to request submissionCommon questions
Can I inquire before the material is decided?
Yes. First write the intended use, quantity, and known dimensions, and select “undecided” in the material field. Suitability is then confirmed against samples and processing conditions.
When inquiring about PS sheet, what should I provide?
First write the intended use, estimated quantity, and a contact method; also send thickness, width, roll diameter, sheet length, or drawings and photos when you have them.
If a page does not list a property, can I order as if that function is included?
No. Please send the required properties and use conditions, and confirm them against the corresponding material reports or samples before proceeding.
Do I need a sample?
When appearance, hand feel, or downstream processing matters, confirm with a sample first. Inquiry information and samples can be prepared together.
PS 片材能不能进冰箱或冷冻？
不建议。PS 在低温下脆性明显，跌落或受冲击时容易开裂。冷藏、冷冻场景建议改用 PET 或 PP，并结合实际温度与结构确认。
HIPS 和 GPPS 怎么选？
看两个条件。要透明度选 GPPS；要韧性、有跌落风险或有卡扣结构选 HIPS。若两者都要，通常需要评估 PET。
PS 片材可以做食品接触包装吗？
不能笼统认定。食品接触是否适用，取决于具体材料牌号、对应检测报告的适用范围与生产批次，采购时应把需要核对的资料单独列明，由供需双方确认后再定。
