Silicone & Custom Elastomer Valves for Food Packaging

Silicone & Custom Elastomer Valves Applications in Food Packaging

Silicone and elastomer valves are widely used in squeeze bottles, dispensing caps, and flexible packaging for sauces and condiments such as ketchup, salad dressing, soy sauce, mayonnaise, mustard, yogurt-based sauces, and plant-based pastes.


Food products vary significantly in viscosity and flow behavior, which directly impacts dispensing performance. In addition, container design, wall thickness, and consumer squeezing habits all influence how the valve performs in real-world use.

To Ensure Optimal Results,

Hopewell Engineers Valves Based on Three Primary Viscosity Ranges:


Low viscosity (<1,000 cP)

ketchup, syrup, edible oil, yogurt sauces

Medium viscosity (1,000–2,000 cP)

salad dressing, BBQ sauce, honey, oyster sauce

High viscosity (>15,000 cP)

mayonnaise, peanut butter, mustard, avocado paste


Each category requires precise matching of valve diameter and slit geometry to balance flow control, sealing reliability, and dispensing smoothness.


Manufactured with platinum-cured liquid silicone rubber (LSR), food grade silicone valves comply with FDA and LFGB standards, ensuring safe, stable, and odor-free contact with food products. With advanced molding and slit-cutting technology, we help global brands upgrade packaging functionality while improving user convenience and product integrity.
