Resealable Bottle Caps

Resealable Bottle Caps

Linseed oil, also known as flaxseed oil, is a high-end oil rich in alpha-linolenic acid (Omega-3 fatty acids), ideal for low-temperature cooking or direct consumption. To match its premium quality and unique usage needs, our resealable bottle caps are engineered with a patented dual-channel design that redefines liquid dispensing. Unlike traditional single-opening caps, these product feature two separate or interconnected channels, completely separating liquid outflow from air intake for unmatched performance.

Frequently Asked Questions
 
 

1. Can repeated opening and closing be tested?

-

Yes. Opening feel and closing stability can be tested according to project requirements.

2. Can secondary sealing and tamper-evident structures be combined?

 

-

Yes, but the tamper-evident ring or tear-off structure needs to be designed according to the bottle neck structure.

3. Is it suitable for liquid products?

 

-

Yes, but the dispensing orifice and sealing method should be tested according to viscosity.

4. Are bottle samples needed?

 

-

Customer bottle samples are needed for inversion, squeezing, and transport simulation tests.

5. Can a child-resistant structure be developed?

 

-

It can be evaluated, but the structure needs to be developed separately and testing standards confirmed.
