Starting a bulk order is straightforward. First send us a detailed RFQ: film type, application, printing technology, thickness, width, roll length, core size, quantity and destination port. We then recommend the right film and provide samples for you to test on your actual line.

Once the sample is approved, we confirm specifications, quotation, MOQ, payment terms, production lead time, packaging and shipping terms, and you sign the purchase order. A standard flow calls for a 30% deposit, with the remaining 70% due against the B/L copy, and production starts about 18 to 25 working days after confirmation. The staged process of specification, sampling, approval, and ordering prevents you from buying film that behaves differently from your real production needs.

Yes. Selected Top-In products carry a six-month warranty, and we provide equivalent compensation for qualifying quality problems, so your purchase is protected beyond the point of delivery. Before you buy for commercial orders, we recommend documenting the warranty scope, quality acceptance criteria, claim procedure, and compensation mechanism.

The contract should clearly state how defective rolls are identified and what evidence, including photos, test reports, and retained samples, supports a claim. Combine this with the approved-sample specification so "quality problem" is judged against the standard you agreed on, not open to interpretation. Our after-sales team responds to inquiries within about six hours and works with you to resolve issues quickly, because our tenet is excellent quality backed by experienced after-sales service. Clear terms up front turn a potential dispute into a straightforward, fair process.

Top-In uses standard export packaging built to survive long ocean freight: cartons, edge protectors (bells), pallets and stretch film, with rolls palletized for safe handling and container loading. Loading guidance is about 10–12 pallets per 20-foot container and 20–22 pallets per 40-foot container for the relevant product ranges, though the exact count depends on roll dimensions, packaging configuration and product weight.

We also adjust packing to suit each market: sturdy carton-and-bell doubles for demanding routes, and packs safe for domestic distribution for local distributors. Before you book freight, request a packing list with estimated gross weight and pallet count so your forwarder can plan accurately. If you need special marking, pallet height limits or mixed-width assortment in one container, tell us at order confirmation and we will configure the load to maximize protection and container utilization.

Lead time depends on product type, order quantity, specifications and current production scheduling, so we quote it per order rather than applying one fixed number. As a guide, product listings indicate roughly 18–25 working days after confirmation and deposit for many films, and around 20 working days for a 40-foot container of selected products. Specialty constructions, custom widths or peak-season volumes may run longer, while stock-standard films can often ship sooner.

Because our nine lines and fifteen slitters let us balance load across plants, we can usually absorb urgent orders with adjusted scheduling. The reliable step is to request a product-specific production schedule when you inquire, including your target ship date, so we can confirm realistic timing and reserve capacity. Planning lead time together upfront prevents the costly surprises of a container that misses your selling window.

Top-In generally trades on T/T (telegraphic transfer), with terms shaped by product type, order volume, our relationship and the commercial agreement. A common structure is a 30% deposit to secure production, with the remaining 70% balance paid against the Bill of Lading copy. So you release the balance only once the goods are shipped and documented. For established partners or larger programs we can discuss adjusted structures.

To avoid any misunderstanding, we need you to confirm all payment details directly in the formal quotation or sales contract before any transfer. These details include the deposit percentage, balance timing, banking information, and the applicable Incoterm. Our beneficiary is Foshan Xinyi Import & Export Co., Ltd., and full bank details are provided on the proforma invoice. Clarity up front keeps both sides protected and lets production start without delay.

Evaluate a Chinese film supplier across five practical areas: manufacturing capability, product quality, certifications, export experience and commercial reliability. Verify factory ownership or real production capability, inspect the equipment, and test samples on your own line rather than trusting photos. Review certificates and confirm they cover the exact product and scope you buy, and check export track record across markets similar to yours.

Top-In, for instance, has shipped to over 53 countries for two decades. For recurring orders, put written quality standards, acceptable tolerances, packaging rules and a clear defective-product procedure into the contract. Delivery performance and after-sales responsiveness matter as much as price, so assess how quickly the supplier answers and resolves issues. This structured approach protects you far better than choosing on the lowest quotation alone, and it sets a measurable basis for a stable, long-term supply relationship.

Wrinkles and curling are usually machine-side or condition issues rather than a defect in the film itself. Common causes include excessive roller pressure, damaged or worn rollers, uneven pressure between the heating and rubber rollers, inconsistent film tension, and operating temperatures or speeds that do not suit the material. Top-In's guidance specifically points to roller pressure, roller-surface damage and tension imbalance as frequent culprits, so troubleshooting should examine both the laminator and the film together.

Begin by checking roller condition and pressure balance, then confirm tension settings and that the film thickness and adhesive match your machine's parameters. Keeping the laminator calibrated and using the correct film for your substrate typically resolves most cases. If problems persist after adjusting the machine, send us your setup details and a sample of the affected roll and we will help identify whether the film structure or the process needs to change.

A thorough factory audit should confirm that the supplier actually makes what it sells. Start with company registration and ownership, then inspect production lines, coating equipment, slitting machines, raw-material storage and the adhesive materials used—at Top-In, for example, EVA glue is sourced from Japan and South Korea. Review the laboratory, QC procedures, warehouse management, stated capacity and export records, and verify that the plant shown is the one producing your product.

For long-term agreements, also examine traceability, complaint handling, production scheduling and backup capacity so a single breakdown cannot stall your supply. Ask to see test reports and certificate scope, and watch a real production run if possible. At Top-In we welcome audits and sample requests precisely so buyers can validate our capability before signing. A well-run audit turns marketing claims into verified facts you can build a partnership on.

The most reliable way to qualify a film is a structured sample test before you commit to volume. Run the sample on your real production line and check adhesion, transparency, gloss or matte appearance, curling, wrinkling, cutting performance, heat resistance and compatibility with your laminator.

For digital printing, test with actual printed sheets, because toner and silicone oil strongly influence bonding and a generic sample can mislead. Record the approved specification, covering thickness, finish, adhesive type, and acceptance limits, and treat it as the quality reference for all future shipments so that incoming film is evaluated against your own standard rather than ours.Pair this with a factory audit to see our lines, coating and QC in person. This disciplined approach turns "it looks fine" into measurable, repeatable criteria and protects you from surprises once a container is on the water.

Yes. Top-In states that its products are SGS certified and are manufactured under statistical process control to keep quality consistent, and individual product listings also reference ISO9001 and CE where applicable. Our films are formulated to meet international environmental and safety standards, which is why they are trusted in export markets across more than 53 countries. That said, certification is one part of supplier due diligence rather than the whole picture.

We encourage buyers to request the latest certificate copies and confirm that the document covers the specific product, factory and production scope they are purchasing. During a factory audit you can also review our QC procedures, raw-material controls and test records firsthand. Treating certification as a verified baseline and pairing it with sample testing and an on-site check gives you the strongest assurance of safe, reliable film for your market.

Yes. Top-In supplies films in a wide range of widths and roll lengths to match different laminators and production needs. For BOPP thermal film, for instance, widths run from roughly 200 mm up to 1,920 mm and roll lengths from 200 m to 12,000 m, with jumbo rolls available for high-volume users. Core sizes are offered in several dimensions to fit your unwind shaft, and we can adjust winding direction and packaging to your line. Because width, length and core directly affect production planning, packaging and container loading, please confirm these specifications before ordering.

Tell us your laminator model and typical job sizes and we will recommend the roll format that minimizes waste and changeover time. For distributors we can also pre-cut multiple widths per container so you receive a ready-to-sell assortment rather than a single size.

Absolutely. Top-In's manufacturing scale and two decades of export experience make us well suited to industrial buyers, distributors and importers. We export to more than 53 countries and regions, with annual capacity around 26,500 tons backed by nine production lines and fifteen slitting machines. Our range spans standard BOPP and PET thermal film through specialty soft-touch, anti-scratch, metallized, holographic and digital films, so a distributor can build a broad portfolio from one accountable supplier instead of sourcing each category separately.

We support recurring supply with consistent batch quality, container-load packaging and reliable lead times, and our sales team responds to inquiries within about six hours. If you are planning a distribution program, share your target markets and product mix and we will propose a stocking plan, pricing tiers and MOQ structure that help you serve your own customers efficiently.
