老宋在浙江嘉兴开了家瓶级聚酯切片贸易行，手上压着一批华蕾牌瓶级切片和CZ-302水瓶级料。上个月饮料厂客户临时换了供应商，那几托料就这么在仓库里躺了快半年。袋子上的字磨花了，标签还是去年的，仓管说"这料再不动，都快过保质期了"。
大宗料行情说变就变，压在仓里的切片不会自己跟着变。
呆滞切片不是货，是趴在账上的负债。
PET这东西，瓶级聚酯切片，说白了就是做矿泉水瓶和饮料瓶的料。它怕啥？怕吸潮、怕结团、怕跟非瓶级料混。跟白糖放潮湿仓库一个道理——料本身没坏，可吸了潮，切粒的时候就容易结团，纺丝或者吹瓶的时候就出问题。更头疼的是PET瓶片级用量极大，行情波动快，你压在仓里一个月，行情跌一跌，残值就跟着跌一截。
大宗料的通病就是——谁都能收，谁都想压价。更头疼的是瓶级PET跟片材级PET摆一起，光靠眼睛分不出来，得测粘度和色度。贩子不懂这套，抓起来看一眼，直接按PET统货给你算，好料卖了个渣价。
说个真事，老宋之前联系过三个收废料的。头一个一听是PET瓶片级，直接说"这料太常见了，统货价给你算"；第二个倒是来，可绕着仓库转一圈，说"你这料批号不清，我只能按回收片价给你算"；第三个更绝，连门都没进，电话里直接说"你自己拉过来，我就这个价"。老宋差点就拉过去了，幸亏同行提醒他，"这种二道贩子，你拉过去他还能再挑你一车毛病"。
统货商的套路，跟收废品大爷的秤差不多——表面上明码标价，暗地里给你少算二十斤。你以为他在帮你清库存，其实他在拿你的好料贴补他的差料。
说白了，他给的价，永远是他转手再卖一刀的价。
科隆新材做PET回收走终端消化路线。瓶片级通用料、华蕾牌瓶级切片、三房巷CZ-302水瓶级、万凯水瓶级，下游瓶厂和片材厂一直在用，收进来分级后直接对口走掉，不压库。IVL、远东新世纪FENC这些进口瓶片料，我们也接——冷门批次进自家改性造粒配方里消化，不挑牌号不挑批次。跟配饲料差不多，主料主料用，辅料掺着用，啥料都不浪费。
定价按粘度、色度、外观分级，干净片出好价，轻微发黄的按改性料收。自有产能和长期客户托底，报价稳，不会行情一跌就翻脸不认人。
大宗料走量快，前提是你得找到真正用它的人。
合作流程走五步：报料、分级评估、上门收货、抵扣货款、结算开票。老宋那批料就是这么处理的——他拍了照发来，标了华蕾牌切片大概二十吨、CZ-302八吨，我们评估完报了价，约了时间上门过磅。回收款直接抵扣了他下个月采购KONICE改性塑料的货款，抵了差不多五万多。仓库清出一排，老宋说"早知道这样，前年就该处理了，哪用压这么久"。
回收不是贱卖，是把压在仓位上的钱，转成能周转的新料。老宋后来把这事跟同行一说，同行才开窍——原来瓶级切片不是不值钱，是没找对真正用它的人。
目前可回收的PET牌号，包括IVL瓶片级通用料、远东新世纪FENC瓶用聚酯粒、华润化学华蕾牌瓶级切片、江苏三房巷CZ-302水瓶级、万凯新材水瓶级（GB/T 17931-2018）等主流编号。形态上都收：呆滞原包料、瓶片边角、注塑水口、透明瓶废品、库存尾料。本色料和有色料分开装，分级价更优。
三个常见误区，给你提个醒——
"PET到处都是，不值钱？"真相是瓶级切片流通量大，找对终端比找贩子强。
"放着等行情回来？"真相是PET吸潮结团，每多放一个月残值掉一截。
"自己拉过去卖省事？"真相是上门收货和送货上门，价格能差出一截。
Old Song opened a bottle-grade polyester chip trading shop in Jiaxing, Zhejiang, holding a batch of Hualei brand bottle-grade chips and CZ-302 bottle-grade material. Last month, a beverage factory client changed suppliers at the last minute, and those trays sat in the warehouse for almost half a year. The lettering on the bags was worn out, the labels were still from last year, and the warehouse manager said, "If we don't move this material, it's almost past its shelf life."
The bulk material market changes instantly; the chips stored in the warehouse won't change on their own.
Stagnant chips aren't goods, they're liabilities lying on the books.
PET this stuff, bottle-grade polyester chips, to put it bluntly, are material for mineral water bottles and beverage bottles. What is it afraid of? Afraid of moisture absorption, clumping, and mixing with non-bottle-grade materials. It's the same as storing sugar in a damp warehouse—if the material itself isn't spoiled, if it absorbs moisture, it easily clumps when cutting, and problems arise during spinning or blowing. What's even more troublesome is that PET bottles use huge amounts and market prices fluctuate quickly. If you keep them in the warehouse for a month, if the market drops, the residual value drops by a bit.
The common problem with bulk materials is—anyone can buy them, everyone wants to lower prices. What's even more troublesome is that bottle-grade PET and sheet-grade PET are placed together, and you can't tell them apart just by looking; you have to measure viscosity and color. Dealers don't understand this trick, just grab a glance and calculate it as PET bulk, and the good material sells at a scrap price.
Let me tell a truth: Old Song once contacted three scrap collectors. The first one immediately said PET bottle flakes and said, "This material is too common, I'll calculate the wholesale price for you"; The second came but circled the warehouse and said, "Your batch number is unclear, I can only calculate based on the recycling price for you"; The third was even worse, not even entering the door, directly saying over the phone, "Bring it yourself, I'll pay this price." Old Song almost pulled it over, but luckily a peer warned him, "This kind of middleman, if you bring it over, they can still find fault with your truckload."
The wholesaler's tactic is similar to the scale of a scrap collector—outwardly the price is clearly marked, but secretly they calculate 20 jin less. You might think they're helping you clear inventory, but actually they're using your good materials to make up for their inferior goods.
To put it bluntly, the price he gives is always the price he would sell for another cut.
Kelong New Materials follows a terminal digestion route for PET recycling. Bottle-grade general-purpose materials, Hualei brand bottle-grade slices, Sanfangxiang CZ-302 bottle-grade, Wankai bottle-grade materials—downstream bottle and sheet factories have always used them. After grading and collecting them, they are immediately taken away without inventory overload. For imported bottle flakes like IVL and Far East New Century FENC, we also accept niche batches and enter our own modified pelletizing formula for digestion, regardless of brand or batch. It's similar to mixed feed: main and main ingredients are used, auxiliary materials are mixed in, nothing is wasted.
Pricing is based on viscosity, color, and appearance—clean sheets get good prices, and slightly yellowed ones are treated as modified materials. With our own production capacity and long-term customers as a backup, our quotes are stable, and we won't turn our backs on anyone when the market drops.
Bulk materials sell quickly, but the premise is that you find people who truly use them.
The five-step cooperation process: material reporting, grading evaluation, on-site pickup, deducting payment, and settling and invoicing. That's how Old Song handled the batch of materials—he took photos and sent them, labeling Hualei brand slices for about twenty tons and CZ-302 eight tons. After we appraised and quoted the price, we arranged a time for on-site weighing. The recycling payment was directly used to offset his purchase of KONICE modified plastic next month, totaling about fifty thousand. After clearing out a row from the warehouse, Old Song said, "If I'd known, I would've dealt with it the year before last, why would I have kept it for so long?"
Recycling isn't about selling cheaply; it's about converting the money held in the warehouse into new materials that can be turned. Later, Old Song told his peers about this, and they finally understood—it turned out bottle-grade chips aren't worthless, but that they hadn't found the right people who actually use them.
Currently, the PET grades available for recycling include IVL bottle-grade general-grade material, Far East New Century FENC bottle-grade granules, China Resources Chemical Hualei bottle-grade chips, Jiangsu Sanfangxiang CZ-302 bottle-grade, and Wankai New Materials bottle-grade material (GB/T 17931-2018). In terms of form, they collect: obsolete original material, bottle chip edges, injection-molded spouts, transparent bottle scrap, and inventory scrap. Packaged separately for this colorant and colored materials, the graded price is better.
Three common misconceptions, here is a reminder —
"PET is everywhere and not valuable?" "The truth is bottle-grade slices have a large circulation volume; finding the right terminal is better than finding a dealer."
"Waiting for market returns?" "The truth is PET absorbs moisture and clumps, and every extra month it holds drops in residual value."
"Is it easier to bring it over and sell it yourself?" "The truth is, the price difference between door-to-door pickup and home delivery can be quite different."
