Initial Buyer Input
The submitted width was 9.6 m. It described the project incompletely and did not confirm the full roof-covering path, fixing zones or installation allowance.

46-Roll PO Greenhouse Film Order for an 8-Span Commercial Greenhouse
How an initial 9.6 m covering request was reviewed against the greenhouse structure, revised to 10.2 m, converted into a five-layer 180 micron film specification, checked during production and recorded for 40HQ loading.

Practical Outcome
The Most Important Correction Happened Before Film Extrusion
The buyer initially submitted a 9.6 m width. That figure did not provide enough confidence for production because greenhouse film width must match the covering path over the frame and the intended fixing method, not simply a ground-level dimension. After the structural information was reviewed, the approved roll width became 10.2 m. This 0.6 m correction removed a site-fit risk before raw material was committed.

Project Brief
A Custom Covering Order for Commercial Tomato Production
The order was prepared for a Central Asian greenhouse builder covering an eight-span commercial greenhouse used for tomato production. The purchasing requirement was not limited to film thickness. The order also had to define the finished covering width, roll allocation, functional additives, functional-layer orientation, fastening method, individual roll handling and container loading.
- Commercial multi-span structure
- Clear roof-covering film
- Lock channel and wiggle-wire fixing
- Anti-drip/anti-fog surface inward
- Individual roll weight: 169–176 kg
- Export packing for 40HQ loading
Specification Decision
How the 9.6 m Request Became a 10.2 m Production Width
A roll that is too narrow cannot be corrected on site. The width was therefore treated as an approval gate, not as a buyer-entered value that could pass directly into the production order.
Structural Review
The supplier reviewed the greenhouse span information, arch covering path and lock-channel fixing method. The film orientation and installation approach were confirmed at the same time.
Production Approval
The finished roll width was revised to 10.2 m and recorded in the approved specification before the production order was released.
Approved Order Specification
What the Factory Was Required to Produce
Every production, inspection and packing record should refer back to the same approved order reference: TF-GF-2026-008.
| Specification Item | Approved Requirement | Why It Was Controlled |
|---|---|---|
| Product | Clear PO greenhouse film | Commercial roof covering for an eight-span tomato greenhouse |
| Film Structure | Five-layer co-extruded PE / LDPE / EVA formulation | Defines the approved film construction and functional formulation |
| Thickness | 180 micron; 170–190 micron acceptance range | Controls material use and mechanical consistency across the roll |
| Roll Size | 10.2 m × 100 m | Matches the reviewed covering width and order allocation |
| Colour | Clear | Supports the required visible-light transmission |
| Functional Package | UV stabilization, anti-drip, anti-fog and thermal option | Matches outdoor exposure and the greenhouse condensation requirement |
| Film Orientation | Anti-drip and anti-fog surface installed inward | Prevents the functional surface from being installed on the wrong side |
| Roll Weight | 169–176 kg per finished roll | Affects handling, loading, roll identification and shipment planning |
| Quantity | 46 rolls; 46,920 m² | Connects the commercial order quantity to the loading record |
| Fixing Method | Lock channel and wiggle wire | Used during the width and installation review |
| Export Packing | Core winding, protected roll ends and woven outer-bag packing | Protects roll edges and film surfaces during export handling |
Four Purchase Decisions
Why the Order Was Not Approved on Thickness Alone
For a commercial covering order, thickness is only one control point. Width, functional formulation, orientation and handling can create equally serious site or delivery problems.
Width Was the First Risk
The 0.6 m correction was resolved before quotation approval because a short roll cannot be repaired after delivery.
Functions Were Named
“Greenhouse film” was not sufficient. UV, anti-drip, anti-fog and thermal requirements were written into the order.
Orientation Was Marked
The functional surface had to face inward, so the requirement was reviewed before roll packing and site installation.
Roll Weight Was Controlled
The 169–176 kg finished-roll range affected handling equipment, packing protection and container planning.
Order Traceability

APR 18
40HQ Loading Recorded
The 46-roll order was recorded for loading in one 40HQ container.

production planning and document traceability. The actual production period ran from April 8 to April 15, 2026.
Production and Inspection Process
What Was Checked During Production and Loading Preparation
The workflow follows film production, thickness review, mechanical testing, optical testing and preparation for packing and container loading.
Batch Quality Inspection
Recorded Results for Order TF-GF-2026-008
The April 12 quality check compared the approved criteria with the recorded batch results for thickness, light transmittance, haze and appearance.
| Inspection Item | Approved Criterion | Recorded Result |
|---|---|---|
| Film Thickness | 170-190 micron accepted range | 176-184 micron - Pass |
| Light Transmittance | At least 91% | 91.2% - Pass |
| Haze | No more than 9% | 7.8% - Pass |
| Appearance | Uniform, clean and without visible defects | Uniform, clean and without visible defects - Pass |
Packing and Shipment
46 Rolls Prepared for Export Handling
The 46-roll order was allocated to one 40HQ container and recorded for loading on April 18, 2026. The roll specification and quantity were tied to order TF-GF-2026-008 and batch Batch260312.
- 46 finished rolls identified against TF-GF-2026-008
- Confirmed specification: 10.2 m x 100 m x 180 micron

Case Study FAQ
Questions About This Greenhouse Film Order
The answers distinguish confirmed order facts from specifications that must be reviewed for a new project.
Why was the film width changed from 9.6 m to 10.2 m?
The initial width did not fully describe the roof-covering path and fixing requirement. The supplier reviewed the greenhouse structure and fastening method before approving 10.2 m as the finished production width.
Does this case mean every commercial greenhouse should use 180 micron film?
No. The 180 micron value belongs to this order. A new project should confirm climate, structure, fastening stress, crop environment, expected service conditions, formulation and handling before production.
Why was Batch260312 created before the physical production date?
The code was established on March 12 during pre-production planning for material allocation, order control and traceability. Actual production ran from April 8 to April 15, 2026.
Which records connect the approved specification to shipment?
The order number and batch number connect the specification confirmation, production order, batch quality inspection, technical data sheet and container loading record.
How were the inspection results connected to the 46-roll order?
The inspection summary uses order TF-GF-2026-008, batch Batch260312 and the approved 10.2 m x 100 m x 180 micron specification, matching the same identifiers used for production and loading.
What information is needed for a similar quotation?
Send the greenhouse dimensions or drawing, covering path, required roll width and length, thickness, climate, crop, expected functions, fastening method, quantity, packing requirement and destination port.
