Custom Plastic PP Square Cream Jar 20g to 100g

Disadvantages and Considerations

1. Product Exposure (Biggest Drawback): Like all open jars, it exposes the entire product to air and potential contamination every time it's opened. This leads to:

   • Oxidation: Degradation of air-sensitive active ingredients (e.g., Vitamin C, retinoids).

   • Contamination: Introduction of bacteria from the user's fingers.

   • Evaporation: Loss of volatile compounds, which can change the product's consistency.

2. Product Waste: It can be difficult to scoop out all the product, especially from the corners, leading to waste.

3. Ergonomics: The corners can be less comfortable to hold than a round jar, though this is often a minor issue.
