Application of PVC packaging film in domestic market
2024-03-19 17:48PVC packaging film is easy to break when printing, not because the quality of PVC packaging film is poor, but because there is a solvent in the printing ink used for PVC that will dissolve the PVC film, and the volatility of this solvent is small. Therefore, if there is too much solvent in the solvent used for PVC ink, the PVC packaging film will dissolve and be broken during printing.
However, if the printing ink for PVC is not used, the printing fastness is not good. PVC packaging film can assemble scattered goods into a whole, and is also suitable for packaging single goods. Secondly, the PVC packaging film is close to the surface of the package, which makes people feel sticky and makes the goods more beautiful, crisp and shiny, which is a wise choice to improve the competitiveness of goods. The important point is that PVC has low input and high output, which is why many businesses choose it. The surface protection of high-shielding products forms a light and shielding surface around the products, thus achieving the goals of dust prevention, water resistance and theft prevention. It is particularly important to compress the film packaging to make the packaged goods evenly stressed and prevent the uneven stress from harming the goods, which cannot be done by the traditional packaging methods (bundling, packaging, tape packaging, etc.).
Lightweight PVC packaging film packaging should become the mainstream trend. Lightweight packaging is beneficial to the environment and the profits of enterprises. Lightweight is a commonly used industrial vocabulary at present, which is used to describe the practice of reducing the weight of packaging by using less materials.
PVC packaging film needs to have good puncture resistance, good shrinkage and corresponding shrinkage stress. In the process of shrinkage, the film cannot produce holes. Since the shrink film is often suitable for outdoor use, it is necessary to add UV anti-ultraviolet agent. Includes OPS/PE/PVC/POF/PET shrink film.
At present, the application of PVC packaging film in the domestic market mainly shows the following characteristics:
1. It is of great significance to apply the combination of heat-shrinkable film and gas-phase antirust technology to replace antirust oil in hardware tools to enhance antirust ability;
2. It has been widely used in fast food, ceramic products, tea sets, mechanical parts and other areas;
3. It can be used for labels of various bottled beer and beverages, which can reduce the process of removing labels and facilitate recycling;
4. Heat shrinkable film is also the patron saint of building and transportation materials. It is not only suitable for the packaging of multiple products and packaging with pallets, but also convenient for transportation and sales, easy to realize mechanization and save labor and material resources, and can partially replace the packaging of cartons and wooden cases;
5, used for bottled beer instead of tying rope packaging to prevent bottled beer from hurting people;
Characteristics of PVC packaging film:
1. It is convenient to use and the working speed is not bad: due to the winding film, it is pre-stretched, which is quite labor-saving, and the unused packaging machine and the used packaging site can be operated by men, women and children. Under the same weight, the length of each roll of this kind of wound film is more than twice as long as that of ordinary wound film, which can reduce the frequency of replacing film rolls during packaging and save costs in transportation, packaging and distribution.
2, no residue: tear off the protective film, there will be no residual text or glue.
3. Non-shedding: the viscosity is 1% higher than that of general enterprise products, and the protective film does not fall off when attached.
4. Non-retraction: environmental temperature difference, surface stretching, resulting in protrusion at both ends. The protective film is made of good quality material. At high temperature, we don't compare it for a while, but look at the long-term quality.
5. Recycling: The wound film can be recycled and granulated in the factory by using general recycling equipment. It can not only reduce environmental pollution, but also save the cost of recycling packaging.
6, no degumming: use glue material, do not let the protective film become a burden that affects product quality.
7. Reduce the overall packaging cost: replacing the traditional stretch wrapped film with film has obviously reduced the total amount of use, so its use cost, transportation cost and storage space cost have all decreased.
The shrink effect of that package is flat, the brightness is good, the film stiffness after shrink is good, and the tightening degree of the package is good. Raw materials are easy to shrink, and the requirements for the shrinkage environment temperature are not high. They can shrink at 40 degrees Celsius, but their strength is greatly affected by the external temperature, and their softness is poor in a low temperature environment.
PVC packaging film According to the product specifications of our factory, choose proper PVC heat shrinkable sleeve film. Install the sleeve film on the package at the temperature of 100℃-160℃ for 6-10 seconds (the actual temperature of the sleeve film is 86℃, and the temperature rise of the package is less than 10℃).
PVC packaging film is widely used in our life. PVC packaging film is made by mixing vinyl PVC resin with more than a dozen auxiliary materials and then inflating it twice. Its use method is to calculate the circumference according to the size of the wrapped object, convert the folding diameter (folding diameter =1/2 circumference), and then enlarge the folding diameter appropriately.
