Why does the covered spring pump core 0.23ml environmental protection vacuum bottle adopt a replaceable PP liner design?

1. Improve product protection and durability
The covered spring pump core 0.23ml environmental protection vacuum bottle adopts a replaceable PP liner design. PP (polypropylene), as a food-grade material, has excellent chemical stability and corrosion resistance, and can effectively isolate the air, moisture and chemicals in the external environment from the erosion of the product in the bottle. This is especially important for cosmetics, skin care products and other products that need to be stored for a long time, to ensure that their quality and effect are not damaged. When the liner needs to be replaced due to long-term use or contamination, the user only needs to replace the liner part without replacing the entire bottle, which reduces the waste of resources and the user's use cost, and improves the cost performance of the product.

2. Enhance environmental protection attributes and market competitiveness
The rest of the bottle can be used for a long time, reducing the generation of plastic waste, which is in line with the pursuit of environmental protection concepts by modern consumers. PP material itself has good recyclability and reduces the impact on the environment. This design also improves the flexibility and applicability of the product. Different products may have different requirements for lining materials. By replacing the lining, the packaging needs of different products can be met, so that the bottle can be applied to a wider range of product types.

3. Improve user experience and convenience
The covered spring pump core 0.23ml environmental protection vacuum bottle adopts a replaceable PP liner design. The liner can be replaced at any time as needed to keep the bottle clean and hygienic, which improves the convenience and comfort of use. The transparent bottle design allows users to clearly see the remaining amount of the product in the bottle, which is convenient for timely replenishment and avoids waste caused by the inability to judge the remaining amount. The patented design of the left and right interchangeable structure makes users more flexible during use, adapts to different usage habits, and improves the user-friendliness of the product.
