Specification Review
Confirm product type, resin, thickness, width, roll length, function, color, packing method and target application before production.
Process Control
Plastic Film Quality Control from Order Specification to Finished Roll
Plastic film quality control starts before production. For custom plastic film orders, material, thickness, width, length, color, function, packing and application requirements should be confirmed before the film is blown, cut, packed and shipped.
Material & Formula Check
Review material and masterbatch requirements such as UV, anti-drip, anti-fog, color, transparency or custom additives.
Film Blowing Control
Monitor the film blowing process, film bubble stability, width, thickness and roll formation during production.
Production Inspection
Check thickness, width, appearance, roll weight and other practical specifications according to the production order.
Functional Testing
When required, optical, mechanical, anti-drip, anti-fog or aging-related tests are arranged according to product type.
Packing Review
Confirm roll packing, woven bag, carton, pallet, label and export packing requirements before shipment.
QC Sampling
The production team checks during manufacturing, while the quality control team performs sampling inspection.
Final Shipment Review
Review finished goods, packing condition, quantity and shipment readiness before delivery or container loading.

Inspection Tools
Testing and Inspection Equipment Used for Film Quality Checks
Inspection equipment supports practical quality checks such as film thickness, tensile performance, optical clarity, haze, transmittance and aging-related evaluation. Final test scope depends on product type and order requirements.
Thickness Checking
Film thickness is checked during production and before shipment according to the confirmed order specification.
Mechanical Testing
Electronic tensile testing supports tensile strength, elongation and related mechanical performance evaluation.
Optical Testing
Transmittance and haze testing can help evaluate clarity and light performance for greenhouse film and clear PE film.
Inspection Items
Quality Checks by Plastic Film Product Type
Different plastic film products require different quality checks. The inspection focus should follow the product application, material, thickness, functional requirement and packing method.
| Product Type | Typical Inspection Focus | Why It Matters |
|---|---|---|
| Greenhouse Film | Thickness, width, light transmission, haze, UV resistance, anti-drip, anti-fog, tensile strength and packing condition. | Supports crop light, outdoor durability, condensation control and stable greenhouse covering performance. |
| PO Greenhouse Film | Transparency, film structure, anti-drip, anti-fog, UV aging reference, mechanical strength and roll consistency. | Used for longer-life greenhouse projects that require stronger optical and functional performance. |
| Mulch Film | Thickness, width, color, perforation, tensile strength, roll condition and packing quantity. | Affects soil coverage, laying performance, weed control and seasonal field use. |
| Packaging Film | Thickness, transparency, width, roll weight, sealing performance and packing appearance. | Helps protect furniture, cartons, pallets, industrial products and warehouse goods. |
| Protective Bags and Covers | Bag size, film thickness, sealing, perforation, appearance, folding and packing quantity. | Supports mattress, sofa, chair, pallet, tire and large product dust protection. |
| Pond Liner Film | Material, thickness, width, tensile strength, puncture resistance and surface appearance. | Important for water containment, lining stability and project durability. |
Greenhouse Film QC
Greenhouse Film Quality Control Focus
Greenhouse film quality should not be judged by thickness alone. For agricultural covering projects, quality control should consider optical performance, functional additives, mechanical strength, aging resistance, roll dimensions and packing consistency.
- Thickness uniformity and confirmed tolerance.
- Light transmission and haze for crop growing conditions.
- UV resistance and aging-related performance by order requirement.
- Anti-drip and anti-fog function when required for humid greenhouses.
- Tensile, elongation, tear or puncture testing when requested.
- Roll width, roll length, roll weight, core and packing method.

Equipment List
Production and Inspection Support
The equipment information below is summarized from factory records and should be used as a practical capability overview rather than a certification statement.
SJ-180, SJ-150, SJ-90, SJ-75, SJ-65, SJ-55, SJ-45 and SJ-35 model ranges for different film specifications.
Thickness gauge, measuring tools and steel rulers support practical dimensional checking.
Electronic tensile testing supports tensile strength and elongation checks for film samples.
Transmittance and haze testing supports clarity and light-related film evaluation.
Xenon aging, anti-drip and related testing may be used for selected film function requirements.
Vacuum leak testing, weighing, packing review and final appearance checks support finished goods control.
The production team checks each production order during manufacturing according to specification.
The quality control team performs sampling inspection before shipment based on order requirements.
Batch Consistency
How We Support Repeat Plastic Film Orders
For repeat B2B orders, consistency depends on confirmed specifications, controlled production records, practical inspection and packing review. Before mass production, order details should be confirmed clearly to reduce misunderstanding and rework.
- Product type, material, thickness and width are confirmed before production.
- Functional requirements such as UV, anti-drip, anti-fog, color or transparency are reviewed.
- Roll weight, core, packing type and label requirements are checked before shipment.
- Sample confirmation or third-party inspection can be arranged when required by the project.
