Metallized film health packaging new perspective

for metallized oriented polypropylene (oriented polypropylene) packaging materials, the ups and downs of raw material prices, faster development speed, and rapid technological innovation mean that the door of a new application field is opening 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 for precise 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 1600 CC/M/24hr 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 enough potential to double the shelf life of products such as health food

the advantages of metallized film highlight the RVG series standard metallized film that was widely used in the market in the past. This 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 producers 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 and use a new material with a 15 micron structure. 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 at the same time. 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

strengthening flexdc* digital control performance metallized film innovation accelerates. According to a foreign manufacturer of lighter metal pair internalized 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, it is believed that the results of directional one-day experiment are inaccurate. Polypropylene material has better water vapor isolation performance, while polyester material can achieve better oxygen isolation performance

of course, some flexible packaging materials with high isolation completely get rid of the production process of opaque metallization, and the technology of producing transparent or translucent packaging film containing micro vacuum coating 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 is coming. Experts believe that although translucent packaging materials can bring novelty to consumers, the cost of using these materials will inevitably rise, and its performance will not necessarily exceed the standard transparent metallized film materials. At the same time, because of the increased contact with light, this material may also lead to the change of the properties of health food. At this time, the corresponding load is the yield load PS

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. But 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, metallized film packaging materials are still the most reliable way to ensure quality
