The main way of joint tech pack

Tech pack the main connection way has two kinds: ( 1) Hot melt lap type. It USES electric hot melt up, machinery, high frequency vibration welding and ultrasonic welding heating methods, such as plastic belt surface heat melting, two with the melted face lap up, under a certain pressure to keep a certain amount of time, after being melted surface condensation, good adhesive plastic belt joint way. ( 2) Sheet metal button. This method is to use tensioner unidirectional ratchet wheel, belt tension, and then put a hasp joint, reoccupy clamp make hasp cover the two layers of tape, and hasp side teeth tooth shape of concave and convex, biting tape does not cause the loose. Hasp is usually made of galvanized sheet, operation according to the strapping tape model adapted to select the specification of the iron buckle. Above several joint is very safe, plastic belt can keep 5% of the tightening force for a long time, does not return, and under a strong external force hit 5% buffer elongation, ensure the safety of the packaging. Because it has no steel band sharp edge, will not cause damage to packing objects, and at the same time in the process of packing and package will not cause any injury to operating personnel.
