Frequently Asked Questions
What makes silicone ideal for food container seals?
Inert: no taste or odor transfer. Flexible: maintains seal over wide temperature range (-40 to +230°C). Durable: won’t crack or degrade like plastic. Dishwasher safe: easy cleaning. Microwave safe: won’t melt or warp. FDA compliant for food contact.
What hardness for food container silicone seals?
Typically 30-50 Shore A: soft enough to create seal when lid is closed, firm enough to maintain shape. Softer (30): better seal on rough surfaces. Firmer (50): better durability, easier lid removal. Design seal geometry for optimal performance.
How do silicone seals preserve food freshness?
Airtight seal: prevents moisture and oxygen exchange. Flexible: maintains seal despite thermal expansion during refrigeration/freezing. Reusable: maintains sealing performance over hundreds of cycles. No degradation: unlike plastic that warps or cracks. Silicone seal = longer food freshness.
