GAG Rigid Film

Plastic China New Material (Zibo) Co., Ltd. is one of the most reliable manufacturers and suppliers of gag rigid film in China. With abundant experience, we warmly welcome you to buy high quality gag rigid film from our factory. Contact us for more details.

GAG Rigid Film is a high-performance three-layer co-extruded polyester film featuring double-sided PETG outer layers and a high-rigidity APET core layer. Combining the strength advantages of APET and the toughness characteristics of PETG, this composite structure is professionally engineered to overcome the common defects of single-layer PET sheets, such as folding whitening, brittle cracking and poor heat-sealing performance. It delivers ultra-high optical clarity, excellent low-temperature impact resistance, outstanding dimensional stability and superior thermoforming flexibility. With a smooth flawless surface, zero haze, and stable printing performance, GAG rigid film can be freely deep-drawn, bent, die-cut and high-frequency heat sealed. It is widely used in high-end transparent blister packaging, gift boxes, cosmetic packaging, electronic product clamshell packaging and food packaging applications, providing high-strength, high-transparency and yield-optimized packaging solutions for global thermoforming manufacturers.

GAG rigid film is developed to meet the demand for high-clarity and high-strength packaging materials in modern packaging industries. Through advanced co-extrusion technology, the film combines the rigidity of PET with the easy forming characteristics of PETG, resulting in a balanced structure suitable for a wide range of packaging processes.

Environmental protection and recyclability

GAG sheet is an environmentally conscious material, composed of APET and GPET-both fully recyclable polymers. Its production process is designed to minimize environmental impact. After its service life, the material can be recycled and reprocessed, aligning with the stringent sustainability and circular economy requirements of the modern healthcare sector.

Good transparent

GAG plastic delivers optical clarity on par with PETG, achieving transparency levels up to 90%. This exceptional see-through quality makes it an ideal choice for high-end packaging where visual appeal and product presentation are paramount.

Excellent processing performance

GAG sheet offers outstanding thermoforming performance with a distinct advantage: it processes at lower temperatures than many comparable materials, leading to direct energy savings. Its strong heat-seal capability ensures secure bonding, while its excellent dimensional stability during forming maintains precise shapes, guaranteeing high yields and consistent production efficiency.

High cost performance

Compared with pure APET or GPET materials, GAG sheets have a higher cost performance due to their composite structure. They can not only meet higher physical performance requirements, but also have advantages in cost control, and are suitable for large-scale medical device packaging applications.

When customers purchase GAG products, they are concerned about issues such as crystal dot flow patterns and whether they will fall or shatter.

1. Raw Material Incoming QC for Pure Raw Material Purity

We adopt 100% virgin APET and PETG polyester pellets with multi-stage impurity filtration before feeding. Raw materials are tested for particle cleanliness, melt uniformity and impurity content to eliminate tiny foreign particles that cause crystal dots, flow lines and surface spots at the source. Raw material toughness indicators are strictly checked to guarantee basic anti-fracture performance.

2. Three-Layer Co-Extrusion Process Control to Avoid Flow Patterns

Closed-loop constant temperature extrusion and balanced three-layer flow rate control are applied during co-extrusion production. Precise screw speed and die pressure adjustment prevent inconsistent melt flow that generates streaks and flow patterns on the film surface. Stable layered combination ensures tight bonding between PETG skin and APET core without layer separation risk.

3. Full Online CCD Defect Scanning to Eliminate Crystal Dots

High-speed full-width CCD online inspection runs through the whole production line, automatically capturing tiny crystal points, fish eyes, flow marks and surface blemishes. Defective sections are marked and cut off in real time, so only flawless film rolls enter the next procedure to solve customers' worries about surface appearance defects.

4. Simulated Drop & Impact Test to Prevent Shattering & Breaking

Each finished batch undergoes targeted drop test, extrusion impact test and bending simulation test to replicate transportation and processing scenarios. The test verifies the composite structure's toughness, confirming the film will not crack, shatter or split after heavy impact or folding, fully addressing clients' concern about insufficient anti-break performance
