HALS UV protection that keeps agricultural film strong through tropical sun, with agrochemical-resistant options for treated crops.
Sunlight breaks down polyethylene. Without protection, agricultural film loses strength and elongation, turns brittle and tears long before the end of the season, especially near the equator, where UV exposure is high all year.
Hindered amine light stabilisers (HALS) protect the film by trapping the free radicals that UV light creates in the polymer, slowing that breakdown. The dose sets how long the film lasts, so it is chosen against the target life of the film, its thickness and the local sunlight.
Agrochemicals are the hidden factor. Sulphur and chlorine-based pesticides and fumigants can deactivate standard HALS and shorten film life sharply. If your customers' crops are treated, specify an agrochemical-resistant grade from the start.

PE / LLDPE · Agricultural and food film
State how many seasons or months the film must last: this sets the dose.
Annual sunlight varies widely, and tropical sites need more protection.
Name the pesticides and fumigants used, so we can choose a resistant grade.
We report UV exposure, tensile retention and elongation, so you can compare grades.
Hindered amine light stabiliser: the main family of UV stabilisers for polyolefin film. HALS traps the free radicals UV light creates in the polymer and slows its breakdown.
Common causes are a UV dose too low for the local sunlight, film thinner than planned, or agrochemicals deactivating the UV stabiliser. Send us a failed sample and details of the crop treatment and we will help find the cause.
Yes. Greenhouse film often combines UV stabiliser with anti-fog (AFG) and an IR thermal modifier (IRT) that keeps night-time heat in. We check that the additives are compatible.
Send us your polymer, process and the problem you want to solve. We recommend a grade and starting let-down, then ship a 1 kg lab sample, 5 kg pilot sample or 25 kg line trial with TDS, SDS and batch COA.
Masterbatch has to prove itself on your extruder, not ours. This is the route every new grade takes.
Polymer, process, the problem to solve, and your current product if you have one.
A grade and a starting let-down for your line, shared with you shortly.
A 1 kg lab sample, 5 kg pilot sample or 25 kg line trial, with TDS, SDS and batch COA.
We review the results with your team and adjust dosage or formulation.
Price, MOQ and lead time fixed against the approved grade.
