The role of heat shrinkable film, how to seal heat shrinkable film

Heat shrinkable film, which shrinks when exposed to heat, thus tightly wrapping the film on the product.

Heat shrinkable film is widely used in: food, medicine, disinfection tableware, stationery and sports supplies, craft gifts, printed matter, hardware and plastic products, first-class machines, electronic appliances and other products packaging, especially in the irregular shape of items or combined (cluster) packaging, not only to meet the moisture-proof and dust-proof, touch-proof and transparent display of goods, but also to increase the attractiveness of the appearance of products, can also be used to replace all kinds of cartons, not only to save packaging costs, but also in line with the packaging trend. Shrink film (bag) can be processed into:

Flat bags, arc bags, trapezoidal bags, three-dimensional bags and other special-shaped bags.

Shrink film has a high degree of flexibility.

It is not easy to break, strong anti-blasting force, strong impact resistance, strong tear resistance, strong tensile force, and can replace box packaging. The shrinkage rate is large, and the items can be tightly wrapped after heat shrinkage, and if it is made into a PE through bag (the two ends of the bag are opened) after heat shrinking, the two ends of the opening can lift the items, which can bear a weight of 15kg and is easy to handle. Good transparency and light transmittance.

Up to 80%, it can display products, can invisibly promote products, and also reduce distribution errors in the logistics link. Moisture-proof, waterproof and dust-proof, which can not only achieve the packaging effect, but also beautiful products and protect products.

Non-toxic, tasteless and non-polluting is an environmentally friendly packaging material.

The first step is to put the book you want to wrap in a shrink bag. The second step is to seal with a hot splint and other similar tools on your hands. The third step is to blow the book with the hot air of a hair dryer to make the film tight.

1.Put your shoes in. 2.

Fold the front and back excess areas with tape and glue them together. 3.Use a hair dryer to turn on the hot air and blow it to him!

until it is close to the shoe. First, wrap the product in heat shrink film, and then use a hair dryer to blow hot air into the item. The heat shrinkable film will shrink when heated, and it can be tightly attached to the surface of the product after natural shrinkage, so as to achieve the effect of waterproof protection for the body packaging.

Please note that the hot air should be blown evenly, not always in one place, so as not to burn out the heat shrink film. In addition, if you don't need the heat shrink film sealing, please blow the unsealed edge first, and then blow the other parts, and then try to put the sealing line at the bottom or in an inconspicuous position, so that the packaging effect will look good in the future.

How to use heat shrink film:

1. We should confirm that the power supply of the heat shrink film packaging machine is several phases, do not use the wrong one, and the power cord should be grounded, and leakage protection should be done to prevent accidents;

2. Do not put your hand into the machine when operating the heat shrink film packaging machine to prevent accidents, if you really want to repair the machine, we can cut off the power supply;

3. The environment used by the heat shrinkable film packaging machine should not be humid to prevent the occurrence of leakage;

4. There is a heating sheet on the heat shrink film packaging machine, which is mainly to heat and bond the heat shrink film packaging machine, and our operators should not put their hands into the position of the heating sheet to prevent burns.

5. When the machine is not in use, please roll the belt back into the belt tray in the belt storage compartment to avoid deformation when used next time.

6. Do not stick oil to the surface of the conveyor roller.

7. Remember to unplug the machine when not in use. Prevent accidents from happening.

8. Do not replace the parts on the machine at will. If there are parts that need to be replaced on the heat shrink film packaging machine, we must repair it by maintenance personnel, not blindly carry out maintenance.

9. The main parts should be lubricated with oil frequently. Accelerates lubrication between parts.

10. Formulate corresponding safety operation procedures.

Operators should operate in accordance with the operating procedures to ensure safety.

Wrap the object with heat shrink film, and then use a hair dryer to blow hot air, do not concentrate a little, need to disperse some, and finally seal the mouth. Heat shrinkable film, which shrinks when exposed to heat, thus tightly wrapping the product. <

The correct way to use the heat shrinkable film: first wrap the goods with heat shrinkable film, and then use a hair dryer to blow hot air on the items, the heat shrinkable film has shrinkage performance when heated, and it can be tightly attached to the surface of the product after natural shrinkage, so as to achieve the effect of waterproof protection of skin packaging.

Pay attention to the hot air when blowing evenly, do not always blow in one place, in order to prevent the heat shrink film from burning. In addition, if the heat shrinkable film does not need to be sealed, blow the unsealed edge first, and then blow other parts, try to put the sealing line at the bottom or in a non-obvious position, so that the effect will look good after packaging.

The heat shrinkable film has three series: temperature resistance 85, temperature resistance 105 and temperature resistance 125, all of which have passed the SGS environmental protection test and comply with the EU RoHS directive. The surface of PVC heat shrinkable sleeve can also be printed with exquisite words or patterns, which can play a role in identification and anti-counterfeiting of products. Our company has six sets (sets) of high-speed gravure printing machines, carefully providing customers with supporting printing services.

UL certified PE irradiation cross-linked heat shrinkable tubing has the advantages of high temperature resistance, high mechanical strength, good chemical resistance, etc., and is widely used as an insulating material for cables, joints, transformers, and inductance coils, and can also be used as an anti-corrosion coating for oil, water, gas and chemical pipelines.

At present, the company has invested a lot of money in the research and development of PET heat shrinkable tubing and successfully sampled, PET heat shrinkable tubing from heat resistance, electrical insulation performance, mechanical properties are much more than PVC heat shrinkable sleeve, more importantly, PET heat shrinkable sleeve is non-toxic, and easy to **, will not have toxic effects on the human body and the environment, more in line with environmental protection requirements. In terms of use, there is not much difference between PET heat shrinkable tubing and PVC heat shrinkable sleeve, which will not increase the user's investment in equipment, and is a new generation of packaging new materials.

Heat shrinkable film, which shrinks when exposed to heat, thus tightly wrapping the film on the product.

The correct way to use heat shrinkable film, first wrap the object with heat shrinkable film, and then use a hair dryer to blow hot air, just look at the shrinkage to the way you want, don't just concentrate a little, disperse some, otherwise it is easy to burn, and finally seal the mouth.

Common heat shrink film sealing methods are as follows:

22x35 under 36 yards, (one bag for one pair).

30x40 up to 36-39, 32x45 over 40-43, 35x45 over 44, 40x50 booties, Step 2: Stuff the shoes into a bag, if there is desiccant, put 1 bag in it.

Step 3: Sealing. If you have a sealing machine, use a sealing machine, if you don't have it, use scotch tape (adhesive tape), and if you don't have one, fold the excess length.

Step 4: Press and hold the seal, use a hair dryer to blow from the toe cap, and when you see the contraction, move it.
