Why Pressure-Sensitive Inliners Matter. Tamper-evident inliners are a critical finishing component for brands that prioritize product protection, consistency, and trust. They add a visible layer of security while supporting freshness and shelf stability.

Enhanced Tamper Protection. The pressure-sensitive design forms a firm, airtight seal that provides clear visual evidence if a container has been opened or disturbed. This added safeguard helps maintain product integrity throughout storage, transport, and retail handling. By incorporating tamper-evident features, you signal professionalism and attention to detail—key factors for wholesale buyers and regulated markets.

Preserve Freshness & Product Integrity. Foam inliners help protect aroma, texture, and quality by limiting exposure to air and moisture. Whether sealing dried flower or concentrate products, these liners provide dependable protection against environmental factors that can impact shelf life. A secure seal helps maintain consistency from packaging through final use.

Supports Regulatory & Retail Expectations. Tamper-evident packaging is widely expected across regulated product categories. Pressure-sensitive inliners offer a straightforward way to meet packaging standards while prioritizing consumer safety and product accountability. Integrating inliners into your process helps reduce risk and demonstrates a proactive approach to compliance.

Protect Your Brand & Reduce Liability. Secure packaging builds confidence. These inliners reinforce your brand’s commitment to quality, transparency, and responsible packaging—helping reduce potential issues related to handling, tampering, or customer concerns. In competitive markets, details matter. Tamper-evident seals help differentiate professional brands from the rest.

The Final Step in Premium Packaging. Complete your packaging with a clean, secure seal that adds protection and professionalism to every unit. These tamper-evident inliners are a simple upgrade with a significant impact on quality perception and product security.

1. Set an inliner inside the jar cap.
2. Fill the jar and screw the cap on tight.
3. The pressure of the cap bonds the inliner to the rim and forms the seal.
4. When the jar is opened, the seal shows it has been disturbed.

Most brands finish their jars with:

• Our glass flower jars and glass concentrate jars
• Strain labels
• Your state's warning labels

Order the inliners and jars together and everything ships in one box.
