GESTER Paper Packaging Testing Instruments is designed in accordance with TAPPI, ISO, ISTA, ect standards, which is widely used in paper and package industries (such as corrugated fiberboard, flexible packaging, lamination, adhesives etc).
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.
GESTER Heat Seal Tester is essential for various industries, including quality inspection, pharmaceuticals, research, packaging, thin film manufacturing, food production, ect.
The GT-N16 MIT Type Paper Folding Endurance Tester is used for determining the folding endurance strength of paper and paperboard using hang type weight method.
Cardboard Stiffness Tester GT-N40 Product Introduction Application: Cardboard stiffness is the test of cardboard bending strength, the use of TABER (TABER) type stiffness tester. Suitable for determining the stiffness of paper and cardboard of low weight and thickness less than 1mm, the cardboard stiffness tester is the international standard common Taber (Taber) type stiffness tester. The instrument is suitable for paper and cardboard bending strength indicators, is the determination of cardboard stiffness of the special instrument. Standards: ISO 5628, ISO 2493-2, GB2679.3, QB/T 1051, GB/T 22364, TAPPI T489 Principle Designed according to the principle of equilibrium of the moment against the center of the rotating axis. The moment required for a piece of specimen, which is clamped vertically to the free end of the specimen, to be bent at an angle of 15° under the set conditions is the degree of the specimen, in units of MN, M. Feature The instrument adopts bilateral measurement and calculates the average value for more accurate data. Equipped with precision bearings to reduce friction. Mechanical structure, economical and practical. Key Specifications Model GT-N40 Measuring range (1-500)mN.m(divided into 7 ranges) Display error ±2% (10% to 90% of the upper limit value for each grade) Variability ≤2% (10% to 90% range of the upper limit of measurement for each grade) Pendulum arm length 100mm Load force arm length 50mm±0.1mm Test speed 200°±20°/min Rated bending angle 7.5°±0.3° and 15°±0.3° Sample size 70mm×38mm (L×W) Environmental Conditions Temperature 20–40℃, Relative Humidity ≤85% External dimension 240 ×230×350 mm (L×W×H) Weight About 15.5kg
