BOPP多少钱一公斤？
这个问题一搜，从十块一公斤到二十五块一公斤，报价差得比厚度还多。有人说我买的十块的国产通用用得挺好，有人说我买的二十五的进口高透明才叫高端。到底差在哪？
说实话，问BOPP多少钱一公斤的人，大概率还没搞懂BOPP这东西不是一个料——通用级、高透明级、热封级、消光级、珠光级，每个分支价格都不一样。你拿通用级的价和高透明比，那不叫比价，叫被忽悠。
BOPP就是双向拉伸聚丙烯薄膜，由聚丙烯双向拉伸制得，高透明、高强度、防潮，常用于包装、印刷、胶带、标签、食品包装。
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。
进口BOPP（外企大厂）
通用级，参考价约15-20元/公斤。包装、印刷、胶带。
高透明级，参考价约18-23元/公斤。高端包装、食品包装、标签。
热封级，参考价约20-25元/公斤。食品包装、复合膜、特殊应用。
国产BOPP（中企大厂）
通用级，参考价约10-15元/公斤。性价比高，包装、印刷、胶带。
高透明级，参考价约12-18元/公斤。高端包装、食品包装、标签。
消光级，参考价约13-20元/公斤。高端包装、标签、特殊应用。
一句话总结：国产通用10-15块，国产高透明/消光12-20块，进口通用15-20块，进口高透明/热封18-25块。你要的是啥厚度和性能，决定了你该在哪一档选。
二、同是BOPP，价差凭什么这么大
BOPP的价格差，主要藏在四个地方。
第一，厚度不同。厚膜便宜，薄膜贵。薄膜需要更高精度，价格更高。
第二，透明等级不同。通用级便宜，高透明级贵。高透明需要特殊工艺，价格更高。
第三，功能不同。通用级便宜，热封/消光级贵。特殊功能需要特殊配方，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。同样是高透明级，进口比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让厚度骗了你
我见过太多采购，比价比到最后选了最便宜的十块的，然后做出来的薄膜强度差、透明差、客户退货，一次损失够买半年的好料。
BOPP采购这行，水比你想的深。三个坑必须绕开：
第一，看拉伸强度和透光率不看牌号。同一个牌号不同批次性能可能波动，拿到料先测拉伸强度和透光率，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。有些贸易商拿普通PP膜当BOPP卖，拿厚膜当薄膜卖。要COA、要厚度检测、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10块，做出来制品次品率5%；B料单价15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——比如要高透明又要高强度、要热封又要防潮、要低成本又要特殊功能——那不是BOPP的问题，是你需要的不是标准BOPP，是改性BOPP。
这时候可以看看宁波科隆新材目前在做的高性能改性BOPP方案，抗静电、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改性BOPP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，BOPP行情一天一个样，丙烯、拉伸剂、功能助剂、汇率都在动。
如果你需要进口、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BOPP这事儿，十块的和二十五的，差的不是十五。
单价是门槛，选对厚度和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出高透明包装薄膜的方案。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 BOPP per kilogram?
A quick search shows quotes ranging from CNY 10/kg to CNY 25/kg — a spread wider than the film thickness itself. Some buyers say the CNY 10 domestic general-purpose film works fine; others insist only the CNY 25 imported high-transparency film counts as premium. Where does the difference really lie?
Honestly, anyone asking "how much is BOPP per kilo" probably has not yet understood that BOPP is not a single product — general-purpose, high-transparency, heat-sealable, matte and pearlescent grades each carry a different price. Comparing a general-purpose quote with a high-transparency one is not price comparison; it is how you get fooled.
BOPP is biaxially oriented polypropylene film, made by stretching polypropylene in two directions. It offers high transparency, high strength and moisture resistance, and is commonly used in packaging, printing, tape, labels and food packaging.
1. Mainstream grade quotes (imported + domestic)
Here are the high-volume grades and reference prices on the market. Figures below are recent market references; live prices are subject to same-day inquiry.
Imported BOPP (overseas majors)
General-purpose grade, approx. CNY 15-20/kg. Packaging, printing, tape.
High-transparency grade, approx. CNY 18-23/kg. Premium packaging, food packaging, labels.
Heat-sealable grade, approx. CNY 20-25/kg. Food packaging, laminating films, special applications.
Domestic BOPP (Chinese majors)
General-purpose grade, approx. CNY 10-15/kg. Cost-effective; packaging, printing, tape.
High-transparency grade, approx. CNY 12-18/kg. Premium packaging, food packaging, labels.
Matte grade, approx. CNY 13-20/kg. Premium packaging, labels, special applications.
In short: domestic general-purpose CNY 10-15, domestic high-transparency/matte CNY 12-20, imported general-purpose CNY 15-20, imported high-transparency/heat-sealable CNY 18-25. The thickness and performance you need decide which tier you belong in.
2. Why do BOPP prices differ so much
The BOPP price gap mainly hides in four factors.
First, thickness. Thick film is cheap; thin film costs more because it demands higher precision.
Second, transparency grade. General-purpose is cheap; high-transparency is expensive. High transparency needs special processing and costs more.
Third, functionality. General-purpose is cheap; heat-sealable/matte grades are expensive. Special functions need special formulations and cost more.
Fourth, brand and origin. Imports carry a premium but offer batch stability; domestic grades offer value but fewer options. For the same high-transparency grade, imported costs 30-50% more than domestic — you pay for quality control and R&D.
3. Procurement pitfalls: don't let the thickness fool you
I have seen too many buyers end up choosing the cheapest CNY 10 film after endless price comparison, only to have the film fail on strength and transparency, trigger customer returns — one loss enough to buy half a year of good material.
Procurement of BOPP is deeper water than you think. Three traps must be avoided:
First, test tensile strength and light transmittance instead of trusting the grade name. Performance of the same grade can fluctuate between batches. Test against the COA before use. Don't listen to salespeople saying "close enough" — close enough is far apart.
Second, watch out for substitution fraud. Some traders sell ordinary PP film as BOPP, or thick film as thin film. Demand the COA, a thickness test and original packaging. Only accept material with all three.
Third, don't compare unit price alone — calculate total cost. Material A at CNY 10/kg yields a 5% defect rate; material B at CNY 15/kg yields 1%. Per finished part, B is actually cheaper.
4. Standard grades not enough? Consider modified solutions
If standard grades always fall short — you need high transparency AND high strength, heat sealing AND moisture resistance, or low cost AND special functions — the problem is not BOPP itself; you don't need standard BOPP, you need a modified BOPP solution.
Ningbo Kolong New Materials is developing high-performance modified BOPP solutions, with grades covering antistatic, flame-retardant, weather-resistant and conductive properties. For special needs, message us for a modified BOPP quote reference — it saves not only money but also trial-and-error time compared with buying base resin and tuning additives yourself.
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. BOPP prices change daily — propylene, stretching aids and functional additives all move.
If you need same-day quotes for specific imported or domestic grades, message us and we will send a live price sheet. No beating around the bush — real numbers.
Final words
For BOPP, the difference between CNY 10 and CNY 25 is not CNY 15.
Unit price is the threshold; choosing the right thickness and performance is the baseline. Don't let the quote sheet fool you — you are not buying one kilogram of plastic, you are buying a solution for making high-transparency packaging film. Do the math per finished part, add in the loss from rejected goods, and you will know who is truly cheap and who is truly expensive.
