ZLDW-B horizontal electronic paper tensile testing machine
This testing machine is a tensile strength testing machine for measuring the tensile strength and breaking elongation of toilet paper, low-weight paper and other similar thin-sheet materials. The testing machine is a single-screw horizontal structure, and its structural parameters and technical performance are in full compliance with ISO1924 / 2-1985 "Determination of Tensile Strength of Paper and Paperboard-Constant Speed ​​Tension Method" and QB / T1670-92 "Microcontrol Electronic Type "Tensile Strength Testing Machine". This testing machine uses microcomputer and electronic measurement and control technology and LCD screen to display the force value, elongation and time to break the sample. After the chuck spacing is selected according to the requirements, the left chuck will be automatically adjusted to the corresponding position; according to the requirement of the standard stretching speed to break within 20s ± 5s, the software automatically adjusts the appropriate speed. Complete functions, high degree of automation, simple structure, easy operation and maintenance.

Maximum stroke of left chuck: 400mm
Sample width: 15mm
Reset accuracy of left chuck: ± 0.1mm
Adjustment speed of left chuck: 150mm / min
Test speed: automatically adjusted according to 20S ± 5S pull-off time
Instrument dimensions (length × width × height): 750 × 340 × 280 (mm)
Net weight: about 70kg
Paper Bag
Standard brown paper bags are made from kraft paper. Tote-style paper bags, such as those often used by department stores or as gift bags, can be made from any kind of paper, and come in any color. Paper bags can be made from recycled paper
Paper shopping bags, brown paper bags, grocery bags, paper bread bags and other light duty bags have a single layer of paper. A variety of constructions and designs are available. Many are printed with the names of stores and brands. Paper bags are not waterproof. Types of paper bag are: laminated, twisted, flat tap. The laminated bag, whilst not totally waterproof, has a laminate that protects the outside to some degree.
