What is the function of PP cream jar
source：www.mxtea.com.cn | Release time：2024-12-03
The PP cream jar (polypropylene cream jar) mainly has the following functions:
1. Protect the contents
Physical protection
PP cream cans have certain strength and toughness, which can effectively prevent cream products from being damaged by compression, collision during transportation, storage, and use. For example, during the transportation of products from the production workshop to the warehouse and then to various sales terminals, even if they experience bumps or stacking, the cream jar can effectively protect the internal cream from external forces.
It can also provide a relatively stable environment for the contents, isolating foreign objects such as dust and impurities from the outside world. Taking some medicinal creams used for skin wound repair as an example, it is crucial to prevent impurities from entering, and PP cream jars can effectively meet this demand.
Chemical protection
PP material has stable chemical properties and is inert to most chemical substances. This allows it to prevent chemical reactions between the active ingredients in the cream and the packaging materials. For example, some beauty creams containing easily oxidizable ingredients such as vitamin C and retinol, PP cream cans can prevent the cream from becoming ineffective due to contact with harmful substances that may be released from packaging materials or chemical reactions with them.
2. Maintain product quality
Good sealing performance
PP cream jars are usually equipped with lids with good sealing performance. This sealing property can prevent the evaporation of moisture in the cream, maintaining the texture and consistency of the cream. Taking moisturizing skincare creams as an example, excessive loss of moisture in the cream can cause it to harden, affecting its effectiveness and product quality.
Good sealing can also prevent external air from entering the can, reducing the possibility of cream deterioration due to oxidation. For example, creams containing unsaturated fatty acids are prone to oxidation, odor, and discoloration when exposed to air. The sealing characteristics of PP cream cans help maintain the freshness of the cream.
Light avoidance
PP material itself has a certain degree of light shielding, although not as good as dark glass and other materials, it can reduce the influence of light on the photosensitive components inside the cream to a certain extent. For some creams containing photosensitive ingredients such as certain essential oils or special medicinal ingredients, this characteristic helps to maintain the stability of the ingredients, thereby extending the shelf life of the product.
3. Convenient to use and store
Easy to access
The opening design of the PP cream jar is reasonable, making it convenient for users to use tools such as fingers or spoons to take out an appropriate amount of cream. For example, when applying hand cream, face cream and other products, users can easily put their fingers into the jar to take out the cream, and can control the amount of cream taken out according to their own needs.
Some PP cream cans also have special designs on their lids, such as flip up and rotating ones, which are not only convenient to open and close, but also prevent the cream from being contaminated to some extent during use.
Easy to store
The shape of the PP cream jar is regular, usually circular or square, making it easy to stack and store. Whether on the shelves in the production workshop or in the dressing table or medicine cabinet at home, they can be arranged well and save space. Moreover, PP material has a relatively wide temperature resistance range and can maintain stability in general indoor temperature environments. It will not deform or affect the quality of internal cream due to slight temperature changes.
