Q: Production process of PP packing belt: First of all, the extruder temperature control is generally between 250 and 280 degrees centigrade. The next is cooling, strip out the head temperature is very high, to immediately enter the water cooling, because of isotactic polypropylene in acute cold conditions easily generated has crystal structure, molecular structure of paracrystals was loose.

Q: The harm of plastic packing belt to human body: The plastic strapping belt is very poisonous to the human body. If you eat it, you will die and never turn over

Q: Polypropylene packing belt edge why will be scared: Usually translucent, colorless solid, odorless, non-toxic. The melting point can be as high as 167 DEG C because of the highly crystalline structure. Heat resistance and corrosion resistance, products can be steam disinfection is its outstanding advantages. Small density, is the lightest general plastic. The disadvantages are low temperature resistance, low impact and easy aging, but can be overcome by modification.

Q: Why is plastic strapping broken?: Is there any quality problem? The packing bags are all made of their own masterbatch. A serious imbalance in the proportion lead to too brittle packing belt. Or stored for a long time, long sunny rain. It might get crispy. Originally, the quality of plastic belt maintenance time is very long, it is a substitute for steel belt in horizontal wet packaging environment. It should be low cost and strong breaking force.

Q: What's the difference between PP strapping and PET packaging?: The above mainly from the material, performance, cost, safety and use of simple analysis of the PET packaging belt, PP packaging belt and steel belt three packaging tape, respectively. In order to facilitate the vast numbers of users with good choice, different packaging belt, packaging different products. Double glow PET belt has been widely used in the steel industry, aluminum, glass, wood, stone, brick and so on.

Q: What band is the most popular packing belt?: I also do logistics. A lot of wrapping film and wrapping tape.Shanghai and the United States packaging products quality is really good. Several friends I know are placing orders with them.

Q: How do you split the straps?: After dressed again will lead to wear into one small mouth, tighten the strap, complete.

Q: What adhesive tape do you use?: Heavy weight wooden cases can be packaged in PET plastic steel belts and steel strips, in which the plastic steel belt is a new strapping belt instead of the steel belt. It is widely used in ceramics, cotton spinning, aluminum, building materials, tobacco and paper industry.

Q: Baling machine; packing belt; tightness adjustment: The adhesive strength of the packing belt is small and loose.1., bonding temperature should be moderate, too high or too low, can not guarantee the effect of adhesion;2. the voltage of the power supply of the fully automatic baler is insufficient, the actual bonding temperature is lower than the preset bonding temperature, and the relevant standard can not be reached. The cable used too long will also affect the voltage;3. 、 the lower bearing of the automatic packing machine has been damaged, and the adhesive temperature is not going;The spring of the 4. pendulum rod fails, the working position can not be reached, and the adhesive area is small;5., the height of the electric steel sheet can not be perfect combination, resulting in deviation of heating position;

Q: What's the difference between a strapping sheet and a steel package?: Metal packing tape surface lubrication, reduce the friction resistance between the strip and strip between packaging and packaging, in order to make the packing strip tightening more firmly; the edge smooth edges, avoid packaging and packaging to scratch the rower. It is wrapped in linen. There are 1 or 2 sets of steel strips in each package (according to the specific type) and bound with iron strips. The raw material is made of high quality cold rolled sheet.
