Double-Sided Foam Tape

A long-term cooperative customer from Europe (customer name: ***) reported that after a one-time purchase of 500,000 rolls of BOPP packaging tape, their factory's slitting equipment experienced issues during use of this batch of tape, including rough cut edges and uneven end faces on some rolls. Upon investigation, it was found that the cutting tape (industrial slitting blades) on the customer's equipment had suffered severe wear after continuous high-load operation, leading to reduced cutting precision. Since the customer's production line operates 24/7 and this batch of tape needs to be packaged and delivered to their downstream large e-commerce logistics warehouse within 4 weeks, equipment downtime for repair would result in a production loss of approximately 80,000 rolls per day. The customer urgently requests our company to provide repair service support to avoid defaulting on the entire order.

Our company swiftly activated the B2B key account after-sales emergency response mechanism, dispatching two senior maintenance engineers with spare cutting tapes and professional calibration tools to arrive at the customer's overseas factory (location: ***) within 48 hours. After confirming the fault on site, the engineers immediately performed the following maintenance services: 1. Conducted shutdown inspections on all 12 sets of cutting blade holders one by one, replacing a total of 36 severely worn industrial cutting tapes; 2. Used a laser tool setter to recalibrate the parallelism of the blade shafts and cutting gaps, ensuring uniform pressure on all blades; 3. Replaced the aged damping springs in the blade holders due to long-term use, and applied special lubricating grease; 4. Provided on-site training to the customer's operators on daily inspection and blade replacement cycle standards. During the maintenance, our company also coordinated with the local partner warehouse to dispatch 500 boxes of equivalent specification replacement tapes as temporary support for the customer's continuous production, avoiding a full production halt.

An overseas customer (company name: ***, order number: ***) purchased a batch of BOPP packaging transparent adhesive tape totaling 50,000 rolls, specification 48mm*100m. During incoming inspection, the customer found that the peel strength of approximately 12,000 rolls was significantly lower than the contract standard (contract requirement ≥2.5N/cm, actual measured values only 1.8-2.0N/cm), causing edge lifting and detachment on the automatic sealing line. The customer immediately filed a quality complaint, requesting return and replacement of the non-conforming products, and compensation for air freight, handling costs, and production stoppage losses. Due to the large quantity, high value, and long-term cooperation relationship, our company attaches great importance to this and has urgently initiated the quality incident handling procedure.

Our company immediately arranged for a quality engineer to have a video conference with the customer, guiding them to conduct retesting according to the ASTM D3330 standard, and requested the return of retained samples for laboratory verification. It was confirmed that the issue was caused by uneven adhesive coating in one of our production batches. In response to the customer's request for return and replacement, we propose the following solutions: 1) For the 12,000 rolls of tape confirmed as non-conforming, we will arrange a full refund and bear the ocean freight for the return; 2) We will immediately reschedule production of 16,000 rolls of BOPP tape of the same specification (including 4,000 rolls as quality compensation), using a preferred adhesive batch and strengthening coating process inspections; 3) The new goods will be shipped by air to reduce the customer's downtime, with air freight costs borne by our company; 4) For the additional manual sorting costs incurred at the customer's factory due to the replacement, we will compensate USD 2,000 through a proforma invoice deduction; 5) The original non-conforming goods will be collected by our designated local logistics partner, and the customer will be authorized to carry out destructive disposal.

A large packaging products distributor in Europe (customer name: ***, order number: ***) purchased 500,000 rolls of BOPP packaging tape (specification: ***) at one time. After arrival at the port, the customer reported that their warehousing and labeling production line workers, unfamiliar with the operation and storage requirements of large quantities of tape, caused about 8% of the tape to develop end-face wrinkles, sticking, and poor unwinding. The customer requested a return or compensation and suspended subsequent reorders.

Our company immediately initiates the after-sales training service process, assigning 2 technical engineers (names ***, employee IDs ***) to fly to the customer's overseas warehouse (address: ***) to conduct a 3-day on-site training. The training content includes: optimal storage temperature, humidity and stacking methods for BOPP tape, tension parameter adjustment for high-speed slitting/labeling machines, emergency handling of common unwinding issues, and revision of standardized SOPs tailored to the customer's existing operating procedures. Additionally, a bilingual training manual (version ***) and remote video guidance support will be provided.

In March 2024, the company purchased a batch of BOPP packaging tape from our company (a total of 500,000 rolls, shipped in 5 40-foot high-cube containers). The customer reported that when used on high-speed automatic packaging lines, large-scale tape breakage and edge curling occurred, causing frequent production line shutdowns. The customer preliminarily determined this to be a tape quality defect and demanded a full-batch return/exchange as well as compensation for production stoppage losses. Due to the large amount involved, our company immediately initiated an emergency technical response.

Our technical team conducted remote diagnosis of the customer's production environment through video conferencing and real-time data sharing. Through item-by-item inspection, it was found that the tension roller parameter settings on the customer's packaging line were higher than the standard tensile strength range of the tape, and the workshop temperature was lower than the recommended minimum application temperature for the tape. The technical team remotely guided the customer to adjust the tension parameters to the standard range, and added insulation measures and a temperature recovery operation procedure in the tape storage area. Meanwhile, our company arranged for technical personnel to remotely guide the customer in on-site sampling and sending samples back to the laboratory for performance re-testing.

A packaging Co., Ltd. in São Paulo State, Brazil, purchased a batch of BOPP packaging tape through a local agent, with a total value of approximately USD 180,000. The specification is 1280mm*4000m, totaling 1,200 rolls, packed in 3 40-foot high-cube containers. The customer reported that during use on automatic carton sealing lines, some tapes produced abnormal noise during unwinding, initial adhesion decreased significantly, and adhesive overflow occurred at cut edges. About 15% of the rolls could not be loaded onto the machine normally. The customer requested a return and claimed losses due to production line stoppages. Due to the large amount and some containers already being opened, the agent could not determine responsibility and requested our company to send a technical team to the site for fault diagnosis and support.

Our company has assigned 2 technical engineers to arrive at the customer's factory within 1 week, carrying portable viscosity testers, thickness gauges, and coil rewinding inspection equipment. On-site, all problematic rolls were inspected one by one, and it was found that the abnormalities were concentrated in layers 3-5 near the paper core within the same production batch. Testing revealed that the adhesive layer thickness deviation exceeded ±3μm, and the release agent coating was uneven. Through linkage with the customer's MES system for traceability, it was confirmed that this batch of tape had incomplete curing before shipment due to temperature and humidity fluctuations in the workshop, not damage during transportation or warehousing. Our technical team immediately initiated an emergency rework plan: low-temperature rewinding was applied to rolls with adhesive overflow to peel off abnormal layers; rolls with insufficient initial tack underwent 48 hours of secondary curing in a constant-temperature room; meanwhile, the tension parameters of the on-site labeling machine were adjusted to avoid unwinding noise caused by slight tape thickness differences. All processing was completed at the customer's warehouse, and full inspection was conducted in advance on the remaining 150 unopened rolls.
