Cosmetics

With the advantages of cost saving, convenient processing, diverse forms of expression, light weight and so on, flexible packaging occupies a place in the cosmetics packaging market. So, what are the applications of flexible packaging in the field of cosmetics?

Today's soft packaging of cosmetics

Due to the above characteristics, flexible packaging was initially used in the cosmetics field to promote disposable products such as experiential packaging, sheet facial mask and supplementary packaging. The bag shaped promotional experience pack is very light, which greatly reduces the luggage weight of short-distance tourists, and it is also a good form of promotion. The use of soft packaging for sheet facial mask not only reduces the final volume to the greatest extent and ensures the safety and health of products, but also with exquisite printing patterns, it can often make consumers' money bags shrink successfully. Speaking of changing clothes, readers who have bought bottled shampoo and its matching changing clothes should deeply understand that changing clothes is much cheaper than bottles.

However, these three application forms have a common disadvantage: they cannot be reused. This shortcoming greatly limits the application scope of flexible packaging in the field of cosmetics. In order to improve this situation, smart packaging designers have added "wings" - self sealing or bottle caps to flexible packaging, making it possible for such packaged products to be used for a long time.

Cosmetics are mostly made of flexible packaging made of composite film, which can directly contact the contents. The main reason is that considering the diversity of cosmetics formula, the flexible packaging is not only required to have excellent chemical stability and high temperature resistance, but also required to have good heat sealing, printability and high gloss, which can not be satisfied by single-layer film. The use of composite film not only retains the advantages of single-layer film, but also overcomes the shortcomings of different materials to the greatest extent.

The future of cosmetic flexible packaging

With the continuous development of the times and the successive introduction of environmental protection regulations in various countries, the demand of cosmetics for flexible packaging is not only limited to the basic performance and function of the packaging itself, but also must take into account factors such as green environmental protection, energy conservation and consumption reduction.

1. Material saving

For packaging practitioners, how to save packaging materials to the greatest extent on the premise of meeting the basic functions of packaging has become a top priority. We are all looking for corresponding solutions and working hard for them. For example, replacing aluminum foil with aluminized film can greatly save the amount of aluminum.

2. Green environmental protection

Flexible packaging is not easy to degrade, and toxic and harmful gases will be generated after incineration. Therefore, people think of adding some fillers to the raw materials that can accelerate the degradation of materials to speed up the degradation reaction of flexible packaging; Or study alternatives to petroleum products, such as polylactic acid particles extracted from corn to replace plastic particles with petroleum as raw materials. In terms of inks and adhesives, water-based inks and solvent-free adhesives are advocated.

3. Development of antibacterial materials

Cosmetics are likely to be polluted in the process of use, such as direct contact with cosmetics by hands, no regular cleaning of cosmetics, etc. in addition, the raw materials used in cosmetics themselves will breed bacteria, so more than 90% of cosmetics will add trace preservatives to the formula, but this cannot guarantee that the bacterial army will not grow. Therefore, the topic of antibacterial plastics has been put on the agenda. Once, some food enterprises used masterbatches containing silver ions to make membrane bags for packaging milk, which has remarkable antibacterial effect, and has no pollution to the environment and no harm to human body. This case is worth learning from.
