Healthy packaging -- a new perspective of the metallized film market

for metallized oriented polypropylene (PP) packaging materials, the ups and downs of raw material prices, faster development speed, and rapid technological innovation mean that a new application field is opening up to it, and this packaging material may even replace the status of polyester materials

as experts initially expected, metallized film helps products produce visual impact on consumers on the shelf, and with the improvement of the performance of metallized oriented polypropylene materials, its opportunities to replace metallized polyester materials as packaging materials are increasing

metallized film is safer and more convenient

the view that real aluminum foil packaging can achieve the same isolation effect as standard metal film materials is more for convenience than an accurate comparison. As for the sealing performance, it is generally believed that the sealing performance of aluminum foil material itself is enough to reduce the permeability of oxygen and water vapor to almost zero

this level of sealing protection has been regarded as a benchmark requirement by the flexible packaging material industry, but in fact, as a standard, it is not as difficult for manufacturers of metal film oriented polypropylene packaging materials as people previously thought

by using metal membrane instead of non-metal membrane, product manufacturers can reduce the oxygen penetration level of the co extruded film with a thickness of 30 microns from 1600cc/m24hr to 70, and the water vapor penetration level from 5g/m/24hr to 0.7. The latest technology can even further reduce the above indicators of packaging materials

at present, some enterprises at home and abroad are carrying out various improvements to improve the quality of the transparent sheet base film, and improve the overall isolation of the metallized layer to reduce the penetration level to close to zero, reaching the same level as the metal polyester material. At the same time, we also try to convince users who use standard metallized oriented polypropylene film that the high-performance alternative products they produce have sufficient potential, Can share health food and other Pu Nai shares (002225 the shelf life of products is doubled.

the advantages of metallized film are highlighted.

in the past, RVG series standard metallized film was widely used in the market. This kind of metallized film is mainly used for packaging materials with a thickness of up to 30 microns, but the new product series is filling the gap left by the original products. Those health food manufacturers who intend to make profits through the use of improved packaging materials have been able to increasingly reduce the use of heavier laminated packaging materials Instead, a new material with a 15 micron/15 micron structure is used. It is said that this improvement has further improved the water vapor and oxygen isolation performance of RVU series products

rmc series packaging materials are also based on oriented polypropylene materials, but they are mainly used in the packaging of products sensitive to oxygen and fragrance, such as health food and cosmetics and skin care products. Both sides of the package are coated with acrylic acid, which means that the insulation performance of the package has been improved, and the package can also be heated and sealed at a lower temperature

in line with these performance improvements, the application scope of material metallization process and finished materials has also been expanded. Even bread products that have traditionally used standard PE grade packaging materials are also using new technologies that combine polymers with the metallization layer in laminated packaging materials. In addition, in some fields, polyester materials are being replaced in order to make the price more competitive

accelerated innovation of metallized film

according to a foreign manufacturer of light metallized oriented polypropylene packaging materials, it is working side by side with a binder manufacturer and is close to realizing the technology of adding the insulation layer to the metallized film in the lamination stage

4 years ago, this field was actually blank. Now, this process can be used to achieve some specific effects: affecting the surface composition of materials to improve flatness and insulation performance; Or improve the hardness of the material to prepare for increased metal bonding. However, as the price of polyester materials is also declining, the choice of materials often depends on what specifications and characteristics of packaging product manufacturers want. Generally speaking, people think that oriented polypropylene materials have better water vapor isolation performance, while polyester materials can achieve better oxygen isolation performance. Of course, some high isolation flexible packaging materials have completely got rid of the opaque metallization production process route, and the technology of producing transparent or translucent packaging films containing micro vacuum coatings has been quite mature in some countries

at present, 70% of the production capacity of the global packaging material market uses the process of physical evaporation coating, and the remaining 30% of the production facilities use chemical vapor deposition technology

metallized film storm approaching

experts believe that although translucent packaging materials can bring novelty to consumers, the cost of using these materials will inevitably rise, and its performance is not bound to exceed the standard transparent metallized film materials. At the same time, because of the increased contact with light, this material may also lead to changes in the properties of health food

European and American markets are slow to accept these transparent isolation alternatives; In contrast, Japan is impatient to adopt these new materials. It is predicted that the scale of the transparent insulating film market in Japan will reach 30000 tons within three years, exceeding the consumption scale of metallized laminates. At present, transparent vacuum coating film is mainly used in map packaging and product capping materials in Europe and Japan

this material can also show its advantages when the product is to be scanned by a metal detector. The acceptance of this product in the U.S. market is relatively slow. However, one of its main uses in the United States is for high-performance water vapor barrier membranes

"let consumers see the product quality clearly," this concept has once again had an impact on traditional values. However, in all these technological innovations, transparent insulation oriented polypropylene materials still play a relatively minor role compared with polyester materials. At the same time, because it can isolate water and oxygen at the same time, the metallized film packaging material is still the most secure and reliable method to fill the silicone oil delivered randomly into the oil seat (or loosen the bolts of the oil cup)
