Why Supermarket Produce Packers Switch to Virgin Black PET
If you run high-speed thermoforming lines for supermarket fruit punnets, salad bowls, or chilled meat trays, you already know the two biggest headaches with cheap black plastic: chemical odors from recycled scrap and brittle trays that crack in cold storage.
At Suzhou Aoshengpu Technology Co., Ltd., we extrude our Food-Grade Black PET (APET/PETG) sheets and rolls strictly from 100% virgin polyester resin inside a dust-free workshop. There is no post-consumer regrind mixed in. The sheet comes off the calender rollers completely odorless, free of black specks or crystal points, and certified under RoHS, REACH, and ISO9001. It is safe for direct contact with washed berries, cut vegetables, and bakery goods.
Shelf Appeal That Moves Fresh Produce Faster
Walk down any grocery produce aisle and you will see why buyers prefer mirror-black trays over standard clear ones:
Sharp Color Contrast: Our high-gloss mirror black surface makes bright red strawberries, dark cherries, blueberries, white button mushrooms, cherry tomatoes, and green salad mixes pop under supermarket LED lighting.
Optional Anti-Fog Coating: Packing moisture-rich produce into supermarket refrigerated display cases often causes water condensation to cloud the packaging. We offer custom Anti-Fog treatment so your trays stay clear of water droplets and appealing on the shelf.
Fruit-Safe, Burr-Free Edges: Soft fruits like ripe peaches and kiwis bruise easily. Our automated slitting knives leave a clean, burr-free edge. Once thermoformed, the tray rims stay smooth and won't slice into delicate fruit skins during transit.
Cold-Chain & Crush Resistance: Formulated with high impact and crush resistance, our PET sheets hold their structural rigidity during cold-chain transportation and supermarket display stacking without splitting at the corners.
Whether you operate high-speed automated pressure thermoforming machines or standard vacuum formers, we slit every roll to match your exact feed width:
Base Material: 100% Virgin Food-Grade PET / APET / PETG
Thickness Range: 0.15 mm – 3.0 mm (tight gauge control across the web for deep-draw 6-cavity cushion inserts and deep berry tills)
Roll Width: Customized up to 1,250 mm
Density: 1.37 – 1.40 g/cm³
Surface Finish: High-Gloss Mirror Black / Custom Anti-Fog Finish

Frequently Asked Questions (FAQ)
Q1: Does your black PET sheet turn thin or tear at the corners during deep-draw thermoforming? A: No. Because we use 100% virgin resin with a stable melt index and keep thickness tolerance uniform across the width, the sheet stretches evenly into deep multi-cavity fruit trays without webbing or pinholes.
Q2: Can we get a free sample roll to test on our thermoforming machine? A: Yes. Tell us your required thickness (e.g., 0.25mm, 0.35mm, or 0.50mm) and width. We provide free sample sheets or small trial rolls—you only cover the courier freight.
