Canton Fair Film Supplier Checklist: 10 Questions to Ask

Why the First Ten Minutes at the Booth Decide Everything

Most buyers walk the fair, collect business cards, and send emails afterward. The problem: by then, every supplier sounds identical. The booth conversation is your one chance to test whether you are talking to the factory that runs the extrusion lines or to a desk that resells someone else’s film — and the difference shows up months later in tolerance, batch consistency and claim support.

Bring this list, ask the same ten questions at every booth, and compare the answers side by side that evening. Vague answers and precise numbers are very easy to tell apart once you hear them in a row.

The 10-Question Checklist

Ask these in order. The first two questions alone will filter out most intermediaries.

Questions 1–2: Capacity and Co-extrusion Layers

Capacity numbers are not bragging — they predict your lead time in peak season. A plant running 55,000+ tonnes a year across 5 lines on a 72,000 m² site can absorb a rush order; a 500-tonne trader cannot. Just as telling is the layers question: a real production team can sketch the structure on paper — outer layer carrying the UV stabilizer package, middle layers for strength, inner layer for anti-drip. If the person across the table cannot explain what is between the layers, they have never stood next to the line.

Question 4: Thickness Tolerance — Ask It the Right Way

Do not ask “do you have 150 mic?” — every booth will say yes. Ask: “If I order film at a nominal 150 mic, what tolerance do you hold across the roll?” Tolerance is where cheap film hides its cost. Film that nominal-runs at 138 mic is 8% less material and measurably less strength and life, even though the invoice says 150. Our range covers 100–200 mic with tolerance stated on the specification sheet, and the thickness you audit is the thickness you get.

Question 3: How a 3–5 Year UV Package Is Actually Tested

A lifespan claim should come with a test story. Two parts matter: accelerated weathering (xenon-arc aging that simulates years of UV in weeks) and real field data from farms in high-UV regions. Ask how the package is adjusted for your market — the stabilizer loading for Northern Europe is not the loading for a desert at 1,500 m altitude. For PO greenhouse film we rate a 3–5 year service life with the stabilizer package matched to your region’s UV index, and we put that rating in the quotation.

Question 9: Samples and Trial Orders in the Right Order

The correct sequence is: take a sample at the fair, run it on one bay or one row, then place a small trial order before committing farm-wide. Any supplier who pushes you straight to a full container is asking you to skip the step that protects you. Our samples are free, and trial orders start from the 1,000 kg MOQ per specification — enough to cover a real block of tunnels and judge the film over a season.

Question 10 — and the Factory Visit After the Fair

Certificates answer document questions; a factory floor answers everything else. If you are already in China for the fair, the plant visit is cheap to add: our works in Henan is reachable from Guangzhou by a short flight, and buyers who visit during the Canton Fair weeks see extrusion, quality control and warehousing in one trip. An SGS-audited factory has nothing to hide on the line — ask to see the QC lab and the thickness gauges.

Book a Meeting at the Booth

Tell us which phase you attend and what you buy, and our export manager will hold a meeting slot — with sample rolls and a factory-direct quotation ready when you arrive. Bring this checklist; we are happy to answer all ten questions in the first ten minutes.
