How to improve the compression resistance of cosmetic jar packaging

Cosmetic jar packaging plays a vital role in protecting product quality, and its pressure resistance is directly related to the safety and integrity of the product during transportation, storage and use. For this reason, it is particularly important to optimize the design and material selection of cosmetic jar packaging.

Optimization of tank structure design
The design of the tank structure is a key factor affecting the pressure resistance. Designers need to comprehensively consider the characteristics of cosmetics, transportation environment and consumer usage habits to carry out targeted structural optimization.
Wall thickness optimization: Moderately increasing the tank wall thickness can significantly improve the pressure resistance. However, excessively thick wall materials will not only increase production costs, but may also affect the appearance of the product. Therefore, during the design process, it is necessary to take into account both economic benefits and aesthetics on the basis of ensuring compression resistance.
Shape design: A reasonable tank shape can effectively disperse external pressure and thereby enhance overall strength. For example, round or oval tank designs can reduce stress concentration and improve pressure resistance.
Reinforcement rib design: Adding reinforcement ribs to the tank body can significantly improve its rigidity and compression resistance. The number, location, and shape of reinforcement ribs should be accurately designed based on actual usage conditions to achieve the best results.

Selection of high-strength materials
The choice of materials plays a decisive role in the compression resistance of cosmetic jar packaging. Here are several common high-strength materials and their characteristics:
Metal materials: Metal materials such as aluminum and stainless steel have high strength and toughness and can withstand large external pressures. However, the production cost of metal materials is relatively high, and some cosmetic ingredients may react with metals, affecting their stability.
High-strength plastics: High-strength plastics such as polycarbonate (PC) and polypropylene (PP) not only have excellent strength and rigidity, but also have good transparency and corrosion resistance. This type of material is widely used in cosmetic jar packaging and is suitable for diverse product needs.
Composite materials: Composite materials such as fiberglass and carbon fiber have the characteristics of high strength and lightweight. Although the cost is higher, they are very suitable for the packaging needs of high-end cosmetics.

Enhanced internal buffering
Adding cushioning materials inside cosmetic jar packaging is an important measure to improve pressure resistance. Reasonable selection and arrangement of cushioning materials can effectively reduce the direct impact of external pressure on cosmetics.
Bubble Pads: Bubble pads are a commonly used cushioning material whose lightweight, soft, and pressure-resistant properties make them ideal. By adjusting the thickness and density of the bubble pad, the pressure resistance needs of different products can be met.
Foam plastic: Foam plastic has excellent cushioning properties and shock-absorbing capabilities, which can effectively reduce the impact of external pressure on cosmetics. Additionally, the foam can be cut and shaped as needed to accommodate tank designs of different shapes and sizes.
