PO Greenhouse Film for Berry Production in Florida, USA
A Florida berry grower moved from imported PE sheeting to 5-layer co-extruded PO greenhouse film — higher light transmission, a 3–5 year UV-stabilized lifespan, and the strength to stand up to subtropical sun and storm season.

Case at a Glance
Quick Facts
Region & climateFlorida, USA — intense subtropical sun, high humidity, and a storm season that stresses greenhouse coverings.
PartnerA berry grower running high tunnels for strawberries and blueberries.
Trial scope5-layer co-extruded PO film, UV-stabilized, with anti-drip treatment.
Trigger eventImported PE sheeting degraded after 1–2 years under strong UV; light transmission dropped and ripening slowed.
OutcomeLonger expected film life (3–5 years), higher light transmission, better protection through the storm season.
Why it worked5-layer co-extrusion balances strength, light transmission and UV stability — a better match for subtropical conditions than single-layer PE.
Background: Covering High-Value Berries in the Subtropics
Florida’s berry season depends on getting light, temperature and protection right inside the tunnel. The grower had been using imported single-layer PE sheeting, which degraded noticeably after one or two seasons — yellowing, losing light transmission, and thinning at stress points during the storm season.
Replacing covering every year or two is expensive, and the light loss was slowing berry ripening at exactly the wrong time of year. The grower wanted a covering that would hold light transmission longer, survive the UV load, and stand up to storm winds — without changing the tunnel structure.

What We Supplied
5-Layer PO Film
Five co-extruded layers combine strength, clarity and heat retention in a single sheet — higher light transmission than single-layer PE with a longer service life.
UV Stabilizer Package
A high-UV stabilizer package tuned for subtropical sun, protecting the film from yellowing and embrittlement across a 3–5 year lifespan.
Anti-Drip Coating
Anti-drip treatment helps condensation spread into a film and run off instead of dripping onto the canopy — reducing disease pressure on berries.
What Changed in the Tunnel
The switch to PO film changed the economics of the tunnel covering. Instead of budgeting for replacement after every year or two, the grower now expects the covering to hold performance for 3–5 years — with higher light transmission through the life of the film, better UV resistance, and the structural margin to face storm season with more confidence.

Why This Approach Worked
💡
Light where it matters
Higher light transmission keeps berry ripening on schedule through the shoulder seasons, when every extra hour of usable light counts.
☀️
UV package for the subtropics
The stabilizer package is tuned for intense subtropical sun, so the film resists yellowing and embrittlement across a 3–5 year lifespan.
🌪
Storm-season confidence
Multi-layer co-extrusion gives better tear and puncture strength, so the covering holds up better through storm-season wind events.
Where the Grower Is Now
PO film has become the grower’s standard covering, re-ordered at the start of each cycle with the same 5-layer spec and UV package. For US buyers, we handle the full export process — including documentation that addresses Section 301 tariff classification for polyethylene film under HTS 3920/3921 — so the landed cost stays predictable.

Quick Answers
Greenhouse Film FAQ
PO (polyolefin) film typically offers higher light transmission and better UV stability than single-layer PE, with a 3–5 year lifespan versus 1–2 years — a better fit for high-value crops in strong-sun regions.
With a high-UV stabilizer package, PO film is typically rated for 3–5 years of service, depending on local UV intensity, installation quality, and how the film is maintained.
Five polymer layers are co-extruded in one process, each with a specific job — strength, clarity, UV protection, anti-drip — combined into a single film that outperforms single-layer sheet.
Multi-layer PO film has stronger tear and puncture resistance than single-layer PE, which helps it hold up better in storm-season wind events — but anchoring and frame condition matter just as much.
Polyethylene film products are classified under HTS 3920/3921, and Section 301 tariffs apply to many Chinese-origin plastic films. We provide the export documentation needed for accurate classification, so buyers can plan landed costs.
Yes — anti-drip treatment is available on PO and EVA films. It helps condensation run off instead of dripping onto the canopy, which reduces disease pressure on berries and other high-value crops.
