ShengAn’s GAG Plastic Sheet Roll is an engineered, multi-layer material designed to overcome the limitations of single-polymer sheets. Through advanced co-extrusion technology, we fuse a core of rigidAPET between two layers of formablePETG. This innovative “sandwich” structure creates a superior sheet that delivers the best of both worlds, enabling the production of complex, deep-draw, and high-clarity packaging with exceptional consistency and fewer defects. It’s the smart choice for demanding thermoforming applications across various industries.

• 3-Layer Co-extruded Structure: PETG / APET / PETG composition for optimal performance balance.
• Superior Impact Resistance: More durable and crack-resistant than plain APET sheets.
• Good Resistance to Oils and Greases: Suitable for a wide range of food and consumer goods.
• Food Contact Compliance: Meets relevant FDA and EU standards for food packaging applications.
• Available in Various Gauges and Widths: Customizable to fit your specific machinery and product requirements.

Advantages of GAG Sheet Rolls

• Excellent Deep-Draw Performance: The PETG outer layers provide outstanding stretch and formability, allowing for the creation of deep, intricate designs without webbing or tearing.
• High Strength & Rigidity: The APET core provides structural integrity and crush resistance, ensuring your packaged products are well-protected during shipping and display.
• Superior Clarity & Gloss: Offers crystal-clear transparency and a high-gloss finish, perfect for retail packaging that demands excellent product visibility and shelf appeal.
• Eco-Friendly & Compliant: Made from 100% recyclable materials and complies with high environmental standards. Ideal for brands committed to sustainability.
• Excellent Printability & Processability: The PETG surface accepts printing and lamination exceptionally well, while the sheet exhibits consistent thermoforming behavior for high production yields.

GAG sheets are versatile and widely used in:

• Industrial Carrier Tapes & Trays: Protective packaging for sensitive components.
• Consumer Goods Packaging: Blister clamshells for electronics, toys, and hardware.
• Food Packaging: Transparent containers for fruits, salads, bakery items, and deli foods.
• Medical Device Packaging: For trays and blisters requiring clarity and formability.

GAG VS APET VS PETG

ميزة	GAG (PETG/APET/PETG)	APET (Amorphous PET)	PETG (Glycol-Modified PET)
Core Structure	Three-layer co-extruded composite	Single-layer homogeneous material	Single-layer homogeneous material
Formability	⭐⭐⭐⭐⭐ Excellent. Ideal for deep-draw and intricate designs without brittleness.	⭐⭐☆☆☆ Fair. Good for shallow draws; prone to cracking on deep draws.	⭐⭐⭐⭐☆ Very Good. Excellent deep-draw capability, but material is softer.
Rigidity / Stiffness	⭐⭐⭐⭐☆ High. The APET core provides excellent structural support and crush resistance.	⭐⭐⭐⭐⭐ Very High. Extremely stiff and hard.	⭐⭐☆☆☆ Low. Softer and more flexible.
Clarity	⭐⭐⭐⭐⭐ Excellent. Crystal-clear transparency and high-gloss finish.	⭐⭐⭐⭐⭐ Excellent. Superior, water-white clarity.	⭐⭐⭐⭐☆ Very Good. High clarity, typically slightly less than APET.
Impact Resistance	⭐⭐⭐⭐☆ High. More durable and crack-resistant than APET.	⭐⭐☆☆☆ Low. Relatively brittle and can crack under impact.	⭐⭐⭐⭐⭐ Excellent. Very tough and shatter-resistant.
Key Advantage	“The Best of Both Worlds”: Perfectly balances deep-draw capability with final-part rigidity.	“Stiff & Clear”: Offers high rigidity, superior clarity, and cost-effectiveness.	“The Tough Performer”: Provides exceptional toughness and easy processability.
Typical Applications	Complex, deep-draw packaging: Electronic trays, large food containers, demanding medical device packaging.	Shallow-draw / clamshells: Blister packs, blister cards, simple trays.	Deep-draw & durable parts: Complex containers, medical trays, components requiring flexibility.

Quick Selection Guide

• Choose GAG When:
  • You need to createcomplex, deep-draw shapes and the final package must havesignificant rigidity and strength for protection during shipping and handling.
  • It is the ideal solution to the problem of “APET is too brittle, PETG is too soft.”
• Choose APET When:
  • Your packaging design isrelatively simple (shallow draw or clamshell) and your top priorities aremaximum clarity, stiffness, and low cost.
  • Example: Simple blister packs for consumer goods.
• Choose PETG When:
  • Your top priorities areextreme toughness and impact resistance, or you need to form very deep, complex shapes where the final part’s rigidity is less critical.
  • Example: Medical device trays that require frequent snap-open lids.
