The Paper Tearing Strength Tester GT-N01B is a high-precision microcomputer-controlled paper tearing strength tester. It measures tearing resistance for paper, cardboard, leather, films, and composites, with pneumatic clamping and automatic release to ensure accuracy. Features include multi-directional testing (MD/CD/undefined), data storage for 100 results, and compliance with ISO, ASTM, TAPPI, and GB standards. Ideal for quality control in packaging, manufacturing, and R&D.
The GT-N69B sealing tester designed for the quantitative and qualitative evaluation of packaging integrity. Utilizing the Vacuum Water Bath (Bubble Emission) method, this equipment is the industry standard for identifying even the smallest leaks in food, pharmaceutical, and medical packaging. Unlike manual alternatives, the GT-N69B automates the entire testing process—from vacuum pull to pressure maintenance and release—ensuring maximum repeatability and strict compliance with international standards such as ASTM D3078.
Brightness Tester is a specialized printing test machine for the brightness, transparency, fluorescence of toilet paper, paper, paperboard, adhesive sticker and surface of carton.
The GT-N69C Leak and Sealing Tester is a specialized instrument for quantitatively determining the sealing and strength performance of various packaging. It measures sealing strength, expansion pressure, and leakage of bags; the sealing of plastic anti-theft caps and flexible tubes; as well as the compressive, breakage, and torsional strength of caps and packaging materials. The system utilizes a positive pressure test principle with stable mechanical control, offering multiple test modes (rupture, creep, pressure preservation) and customizable ranges (standard 0-600 KPa) and fixtures. It is designed to meet relevant international and industry standards.
