PETG多少钱一公斤？
这个问题一搜，从十五块一公斤到四十六块一公斤，报价差得比透明度还多。有人说我买的十五的华润CR-5083用得挺好，有人说我买的四十六的伊士曼VX301才叫高端。到底差在哪？
说实话，问PETG多少钱一公斤的人，大概率还没搞懂PETG这东西不是一个料——通用级、高透明级、食品级、挤出级、吹塑级，每个分支价格都不一样。你拿通用级的价和吹塑级比，那不叫比价，叫被忽悠。
PETG就是聚对苯二甲酸乙二醇酯-1,4-环己烷二甲醇酯，高透明、高韧性、易加工，常用于化妆品包装、食品容器、家电外壳、医疗器械、3D打印耗材。
一、主流牌号报价（外企+中企）
先把市面上走量的牌号和参考价摆出来。以下为近期市场参考价，实时价格以当日询价为准。
韩国SK（SK Chemicals，韩国）
KN200，高透明易脱模，参考价约23元/公斤。通用注塑、化妆品包装、食品容器。
KN100，注塑级透明食品级，参考价约22.5-23元/公斤。食品包装、化妆品、日用品。
K2012，挤出级，参考价约20.5元/公斤。挤出、片材、薄膜。
S2008，食品包装级不含双酚A，参考价约22.3元/公斤。食品包装、化妆品、日用品。
T95，高透明级，参考价约29.5元/公斤。高端透明制品、光学应用。
伊士曼（Eastman，美国）
DS1010，高透明高韧性包装级，参考价约11-22.6元/公斤。包装、体育用品、日用品。
AN004，光学透明级，参考价约20元/公斤。光学应用、高端透明制品。
VX301，吹塑级透明耐低温耐水解，参考价约46元/公斤。吹塑、高端包装、耐化学应用。
常州华润（中国）
CR-5083，高透明抗冲击食品级，参考价约15.5元/公斤。化妆品包装、食品容器、日用品。
国产PETG（其他中企）
通用级，参考价约12-22元/公斤。性价比高，通用注塑、化妆品包装、日用品。
高透明级，参考价约15-25元/公斤。高端透明制品、光学应用。
一句话总结：国产通用12-22块，国产高透明15-25块，进口通用20-29块，进口高端22-46块。你要的是啥透明度和用途，决定了你该在哪一档选。
二、同是PETG，价差凭什么这么大
PETG的价格差，主要藏在四个地方。
第一，CHDM含量不同。CHDM含量20%左右便宜，含量50%以上高透明但贵。CHDM含量越高，透明度和韧性越好，但价格越高。
第二，用途不同。通用级便宜，吹塑级/光学级贵。特殊用途需要特殊配方，价格更高。
第三，食品级认证不同。通用级便宜，食品级/医疗级贵。特殊认证需要额外测试，价格更高。
第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但牌号少。同样是通用级，伊士曼比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让透明度骗了你
我见过太多采购，比价比到最后选了最便宜的十二的，然后做出来的制品透明度差、有雾度、客户退货，一次损失够买半年的好料。
PETG采购这行，水比你想的深。三个坑必须绕开：
第一，看雾度和熔指不看牌号。同一个牌号不同批次性能可能波动，拿到料先测雾度和熔指，和COA对得上再用。别听销售说"差不多"，差不多就是差很多。
第二，警惕以次充好。有些贸易商拿PET当PETG卖，拿低CHDM含量当高含量卖。要COA、要CHDM含量检测、要原厂包装，三证合一才敢用。
第三，别只比单价，算综合成本。A料单价12块，做出来制品次品率5%；B料单价22块，次品率1%。算到每件制品上，B料反而更便宜。
四、标准牌号满足不了？看看改性方案
如果你发现标准牌号怎么选都差点意思——比如要高透明又要耐化学、要食品级又要抗静电、要低成本又要光学级——那不是PETG的问题，是你需要的不是标准PETG，是改性PETG。
这时候可以看看宁波科隆新材目前在做的高性能改性PETG方案，增韧、增强、抗静电、耐化学这些方向都有对应牌号在做。有特殊需求的可以私信要一份改性PETG的报价参考，比自己买基料再加助剂调试，省的不只是钱，还有试错的时间。
说白了，标准料是大锅饭，改性料是定制菜。你的制品要求越高，越需要定制。
五、常用牌号，私信给你当日报价
上面的价格都是参考价，PETG行情一天一个样，对苯二甲酸、乙二醇、CHDM、汇率都在动。
如果你需要韩国SK、伊士曼、常州华润、国产这些品牌的具体牌号当日报价，私信我，发你一份实时价格表。不绕弯子，报实数。
写在最后
买PETG这事儿，十五的和四十六的，差的不是三十一。
单价是门槛，选对透明度和用途才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出高透明化妆品包装的方案。把账算到每件制品上，再加上次品退货损失，你才知道谁真便宜谁真贵。

How much is PETG per kilogram?
PETG is not one material: high-transparency, food-grade, extrusion, blow-molding, and each carries a different price.

2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) application — premium grades need special formulations and cost more. (3) application — special applications need special formulations or certification and cost more. (4) Brand and origin — imports carry a premium but offer batch stability; for the same grade, imports cost 30-50% more than domestic, paying for quality control and R&D.
3. Procurement pitfalls
The cheapest material often fails on performance and triggers customer returns. Three traps to avoid:
First, test key properties against the COA instead of trusting the grade name — performance of the same grade can fluctuate between batches. Second, watch out for substitution fraud: some traders pass off cheaper or recycled material as the real thing; demand the COA, a test report and original packaging before use. Third, don't compare unit price alone — calculate total cost per finished part, including rejected-goods loss; a higher-priced grade with a 1% defect rate is often cheaper than a low-priced one with 5% rejects.
4. Standard grades not enough? Consider modified compounds
If standard grades always fall short — for example you need flame retardancy AND high transparency, reinforcement AND chemical resistance, or low cost AND food grade — you don't need standard PETG, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PETG solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PETG quote reference — it saves not only money but also trial-and-error time.
In plain terms: standard grades are a big pot of shared rice; modified compounds are a dish cooked to order. The higher your requirements, the more you need customization.
5. Popular grades — same-day quotes via message
All prices above are references; PETG prices change daily as feedstocks and exchange rates move. If you need same-day quotes for specific grades, message us and we will send a live price sheet. No beating around the bush — real numbers.
Final words
Unit price is the threshold; choosing the right grade and performance is the baseline. Do the math per finished part, add rejected-goods loss, and you will know who is truly cheap and who is truly expensive.
