Food packaging bags can be seen everywhere in our lives, such as: candy packaging bags, instant noodle packaging bags, small snack packaging bags, etc. Traditional food packaging easy-to-tear processing methods are mainly manual and mechanical processing. With the development of laser technology, laser marking machines are applied to easy-to-tear mouths. Below, Leapion Laser introduces the laser marking machine on the easy-to-tear food packaging. Application situation.
1. The appearance must not have any defects such as bubbles, perforations, water lines, violent tendons, poor plasticization, fish-eye stiffness, etc. that are obstructive to use.
2. The specification, width, length and thickness deviation should be within the specified range.
3. The physical and mechanical properties include tensile strength and elongation at break, which reflect the ability of the product to be stretched during use. If this item is unqualified, the food packaging bag is prone to cracking and damage during use.
However, the existing easy-tear processing methods are mainly manual and mechanical processing. The manual production is not only inefficient but also greatly increases labor intensity;
Moreover, the existing easy-to-tear processing device is basically a hole punch or a punching machine, and the use of a punch or a punching machine to process the easy-to-tear opening still has the disadvantages of low work efficiency, fixed mouth shape, and high labor intensity.
1. The laser marking machine technology cuts the dotted line on the flexible packaging bag according to the demand.
The processing method is: using the light beam generated by the laser, by focusing on the designed easy-tear line, a thin line with a depth of only a few microns is uniformly cut out. This line destroys the outer packaging of the composite film and retains the inner packaging. It does not damage the packaging function, but also allows the opening of the packaging bag to be torn along the easy-to-tear line regularly during tearing.
2. The laser marking machine has clear and beautiful marks, durable and wear-resistant, and is not easy to be altered and covered, which plays a role of anti-counterfeiting to a certain extent;
The laser beam under computer control can move at a high speed (speed up to 7000mm/s), and processing a conventional product can be completed in a few seconds.
3. The laser processing adopts non-contact processing, so it will not cause damage to food packaging bags, and the machine itself will not wear out. This non-contact processing method greatly guarantees the reliability during high-speed processing. .
4. The laser marking system is equipped with a computer control system, which can flexibly cooperate with the high-speed assembly line, which greatly improves the processing efficiency.
