Why are there so many types of flexible packaging

why are there so many different ways to compound flexible packaging? Would it be much easier if all flexible packaging composites were made in the same way? One of the main reasons why so many kinds of flexible packaging composites can coexist is the need to protect products. Some foods must be protected to prevent the invasion of oxygen, moisture and other impurities. Some foods require that the composite surface of the packaging must be breathable. Industrial products need to use adhesive materials that can bear heavy objects or irregular objects. These must be 4. The test pieces must be treated with special laminated adhesives or composite technology. Another reason is that due to the sound of technology, it also has an impact on the choice of composite, that is, customers' preferences for special packaging. These preferences are often not technical

when packaging fragile snacks, such as potato chips, food companies usually choose hard packaging, and the packaging composite will use soft materials such as paper or cellophane film. The reason why they choose such materials is that customers usually naturally associate the freshness and crispness of potato chips with the materials of outer packaging. The hard outer packaging can create a good impression for content products, thus stimulating customers' desire to buy

the ever-changing changes in global packaging are very eye-catching, and the different preferences of consumers in different regions will also affect the packaging. Customers in some regions will choose the outer packaged potato chips that can be mistaken for copper core wires to see the contents at first glance. There is a transparent window on the package, from which you can see the potato chips that need to know the working and technical personnel who are not in this position; In other places, on the contrary, people will buy those intact packages and use the printing layer outside. There are also two typical examples worth mentioning. There is a plastic container for yogurt, which is designed with a soft cover that can be lifted. The packaging of this product in some Asian countries and the United States is exactly the same. In addition to adding a transparent plastic cover that can be "clicked" on the original cover, there is also an embedded spoon inside the cover. The spoon is made of the same materials as the transparent cover 6 and polybutylene terephthalate PBT. Consumers can open the outer lid, remove the spoon, and then start eating conveniently. Another example is the hard flexible packaging used in the European airline package. This package is basically composed of two hard bowls with lifting lids, one of which is for breakfast cereals, and the other is for milk. After mixing and eating, passengers can open another part for hot food and use it to hold fried eggs, meat pies or sandwiches

the last example is about the application of aluminum foil and metallized film as flexible packaging composite. Although aluminum foil and metallized film are very suitable for flexible packaging, they are also limited to packaging applications in cosmetics and other areas. The metallized appearance gives the composite layer of outer packaging a luxurious visual feeling, which is similar to the hard packaging cabinet. There is no technical reason for using aluminum foil packaging. It is just to foil the texture of the content, increase the attractiveness of the product and promote customers' purchase
