High-precision mold technology: ensure the tight fit and sealing performance of disposable pp sauce portion cup

1. The role of high-precision molds: ensure the precise size of each product
The sealing performance of disposable pp sauce portion cup depends on the close fit between the cup lid and the cup body. Any dimensional deviation may cause the lid to be unable to close firmly, thus affecting the sealing effect. The use of high-precision molds for production can ensure that the dimensional error of each sauce cup is controlled within the micron range, ensuring the smoothness of the cup edge and the precise docking of the lid, thereby forming a firm seal.

In the traditional low-precision production process, due to the limited mold precision, the cup body and the cup lid may become loose or misaligned when buckled, causing the sauce to leak during transportation. The application of high-precision molds can effectively solve this problem, allowing the cup lid and the cup mouth to achieve seamless fit and provide higher sealing reliability.

2. Precision mold design: optimize the matching degree between the cup lid and the cup body
In order to ensure the sealing of the disposable pp sauce portion cup, high-precision molds usually adopt the following optimization designs:

Precisely control the thickness of the cup mouth and the depth of the cup lid slot: The high-precision mold can control the thickness of the edge of the cup mouth, so that it perfectly matches the slot structure of the lid, forming a tight physical closure effect to prevent liquid from leaking from the gap.
Evenly distributed lock design: The cup lid made of high-precision molds is equipped with multiple evenly distributed micro locks at the edge. These locks can provide additional fixing force when buckled, making the lid not easy to loosen, and can still maintain a stable seal even if it is squeezed or shaken externally.
Smooth mold molding process: The PP sauce cup produced by high-precision molds has a smooth surface and no burrs, which not only improves the combination of the cup lid and the cup body, but also optimizes the user experience, making the opening and closing of the lid smoother.

3. High-precision molds help food safety and environmental protection
Sealing not only affects the convenience of the sauce cup, but also directly affects food safety. The disposable pp sauce portion cup made of high-precision molds can effectively block air and bacteria, prevent external contaminants from entering food packaging, and ensure the hygiene and safety of food. In addition, since the PP material itself has good high temperature resistance and corrosion resistance, combined with the sealing structure formed by precision molds, it can maintain a stable sealing effect in different environments, whether it is refrigerated or heated food, it can keep the food fresh.

4. Applicable to a variety of application scenarios to meet market demand
The disposable pp sauce portion cup produced by high-precision molds is widely used in various food packaging scenarios, including:

Fast food chains: ensure that the sauce does not leak during takeaway delivery and improve customer experience.

Catering takeaway industry: high sealing reduces complaints caused by leakage and enhances brand reputation.

Pre-packaged food in supermarkets: long-term storage still maintains a good sealing state to ensure food safety.

Airline catering: prevent leakage caused by changes in air pressure to ensure passengers' dining experience.

Whether it is a catering merchant or a consumer, choosing a PP sauce cup produced by a high-precision mold means that you can get a safer, more reliable and more environmentally friendly food packaging solution.
