PBAT多少钱一公斤?
这个问题一搜,从十二块五一公斤到三十四块一公斤,报价差得比降解速度还多。有人说我买的十二块五的蓝山屯河TH801T用得挺好,有人说我买的三十的巴斯夫C1200才叫高端。到底差在哪?
说实话,问PBAT多少钱一公斤的人,大概率还没搞懂PBAT这东西不是一个料——吹膜级、注塑级、食品级、挤出级、高熔指级,每个分支价格都不一样。你拿吹膜级的价和食品级比,那不叫比价,叫被忽悠。
PBAT就是聚己二酸对苯二甲酸丁二酯,全生物可降解塑料,柔软、韧性好,常用于可降解包装袋、地膜、一次性餐具。
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。
巴斯夫(BASF,德国)
Ecoflex C1200,全生物可降解热塑性聚酯,参考价约27.8-30元/公斤。环保包装、农业薄膜、一次性餐具。
BX8145,食品级吹膜级,参考价约30-35元/公斤。食品医疗包装、高端薄膜。
F Blend C1200,共混级,参考价约28-32元/公斤。通用薄膜、包装。
金发科技(Kingfa,中国)
EBAG-262,挤出级可生物降解,参考价约18-25元/公斤。日用品、办公用品、厨房用品、包装袋。
FLEX-262,挤出级优异柔韧性,参考价约18-25元/公斤。薄膜、包装、柔性制品。
蓝山屯河(中国)
TH801T,挤出吹膜级,参考价约12.5-34元/公斤(不同渠道差异大)。薄膜、管道、瓶子、吹塑。
THJS-5801,食品级吹塑薄膜增韧,参考价约18-25元/公斤。食品医疗包装。
THJS-6801,餐具吹膜级地膜用,参考价约18-25元/公斤。注塑、吹塑瓶子、软管。
THJS-6802,通用级,参考价约18-25元/公斤。通用注塑、薄膜。
国产PBAT(其他中企)
国产通用吹膜级,参考价约18.91-23.8元/公斤。性价比高,通用薄膜、包装。
国产注塑级,参考价约18-22元/公斤。一次性餐具、日用品。
一句话总结:国产通用12-25块,金发/蓝山屯河18-25块,巴斯夫28-35块。你要的是啥用途和认证,决定了你该在哪一档选。
二、同是PBAT,价差凭什么这么大
PBAT的价格差,主要藏在四个地方。
第一,用途不同。吹膜级便宜,注塑级适中,食品级/医疗级贵。特殊用途需要特殊认证。
第二,熔指不同。低熔指适合吹膜价格适中,高熔指适合注塑和薄壁价格略高。熔指决定加工方式。
第三,降解性能不同。通用级降解速度适中价格便宜,快速降解级价格贵。降解速度由配方决定。
第四,品牌和产地。进口溢价高但批次稳定,国产性价比高但质量参差。同样是吹膜级,巴斯夫比国产贵50-80%,贵的是品控和研发。
三、采购避坑:别让降解率骗了你
我见过太多采购,比价比到最后选了最便宜的十二块五的,然后做出来的薄膜强度不够、降解不达标、客户退货,一次损失够买半年的好料。
PBAT采购这行,水比你想的深。三个坑必须绕开:
第一,看熔指和降解率不看牌号。同一个牌号不同批次性能可能波动,拿到料先测熔指和降解率,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PE当PBAT卖,拿部分降解当全降解卖。要COA、要降解检测报告、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12.5块,做出来薄膜次品率5%;B料单价20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——比如要阻燃又要可降解、要增强又要低成本、要抗静电又要食品级——那不是PBAT的问题,是你需要的不是标准PBAT,是改性PBAT。
这时候可以看看宁波科隆新材目前在做的高性能改性方案,PBAT增韧、阻燃、耐候、导电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,PBAT行情一天一个样,BDO、PTA、己二酸、汇率都在动。
如果你需要巴斯夫、金发、蓝山屯河、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PBAT这事儿,十二块五的和三十四的,差的不是二十一块五。
单价是门槛,选对用途和降解性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料,是一公斤能做出可降解制品的方案。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。

2. Why prices differ so much
Four factors: (1) application — lower levels are cheaper; higher levels give better performance but cost more. (2) melt flow index — 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 PBAT, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PBAT solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PBAT 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; PBAT 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.
