In the lubricant industry, packaging safety plays a very important role for the brand.

For the 4L F-type square tank oil packaging, the metal iron lid structure directly affects the leak-proof performance, anti-counterfeiting capability and end-user experience.

For the requirements of oil packaging:

Leak-proof sealing

Anti-vibration performance during transportation

Long-term storage stability

Oil packaging needs to be leak-proof, shock-resistant and have long-term storage stability.

The reinforced iron cover ensures stability during maritime transportation and long-distance transportation, and does not leak.

Technical highlights

This metal cap device has the following functions:

Strong torsional resistance

The seal remains stable even after multiple operations

Strong leak prevention ability

Strong sealing ability

High-quality iron covers are not a cost, but a long-term investment for stable market growth.
