Ultimate tensile strength
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Quality without compromise
Premium flexible film is measured before it protects your product.
From the plant floor to the lab, PKG focuses on film quality that can be evaluated, documented and trusted. Testing discipline gives packaging buyers more confidence in every roll, bag and substrate.
Testing matrix
Film quality viewed from every practical angle.
PKG’s testing lab supports packaging performance with a suite of evaluations that help confirm strength, handling, converting behavior, appearance and roll consistency.
Puncture resistance
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Tear strength
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Dart impact
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Elongation
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Optical properties
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Gauge uniformity
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Sealability
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Roll conformity
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Ink adhesion
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Coefficient of friction
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Vacuum chamber testing
Used to evaluate how the film behaves in production, converting, filling, storage, shipping or finished-package presentation.
Food and sensitive applications
Film quality matters most when the product matters most.
For edible food packaging, PKG supports FDA-compliant film options where appropriate. Produce bags can be vacuum chamber tested, and analytical equipment can help verify material identity and performance alignment.
Food-focused confidenceSupport for food-grade bag and film structures where suitable materials and performance checks are essential.
Roll and line behaviorQuality checks help reduce avoidable downtime, rejects, rework and customer frustration.
Tailored to the applicationProducts can be built around customer needs rather than forced into a commodity-film template.
Quality workflow
A disciplined path from specification to shipment.
Quality is strongest when it is built into the process, not treated as a final inspection event. PKG’s approach connects application requirements, production controls and lab evaluation.
Specification
Confirm film dimensions, resin needs, test expectations, packaging function and customer requirements.
Production control
Use recipe, monitoring and gauge-control discipline to support consistent manufacturing.
Testing
Evaluate the film against relevant mechanical, optical, seal and handling properties.
Documentation
Support ongoing procurement and production confidence with quality-focused communication.
Quality matters

Quality FAQs
Questions about testing and compliance.
These answers help buyers understand how PKG approaches performance and quality assurance.
PKG testing capabilities include ultimate tensile, puncture resistance, tear strength, dart impact, elongation, optical properties, gauge uniformity, sealability, roll conformity, ink adhesion and coefficient of friction.
PKG supports FDA-compliant film options for edible food item packaging where the application requires suitable food-contact materials.
Testing helps verify that film performs as expected before it enters a production line, shipping environment or customer-facing package.
