CHILD-RESISTANT BLISTER

29/12/2023

 

Child-resistant blister packaging is designed to prevent young children who may be curious and explore their environment from accessing and potentially ingesting harmful substances such as medications, yet remain relatively easy for adults to access.
Blister packaging refers to a type of packaging that consists of a plastic or aluminum sheet with individual compartments (blisters) that hold the product, such as pills or capsules. The packaging is typically sealed with a foil or plastic backing.
Several methods and features are commonly used in child-resistant blister packaging such as:


1.    Blister Design:
- Special Shapes: Blister packs may have unique shapes that make them challenging for small hands to grasp and open.
- Multiple Compartments: Dividing the blister pack into multiple compartments can add complexity to the opening process.


2.    Mechanical Features:
- Child-Resistant Closures: Some blister packs incorporate child-resistant closures that require a specific combination of movements or forces to open.
- Slider Mechanisms: Blister packs with slider mechanisms can be designed to require simultaneous actions or specific sequences to open, making it more difficult for children.


3.    Material Choices:
- High-Density Materials: Using high-density materials for blister packaging can make it more resistant to tampering or accidental opening.
- Special Laminates: Packaging materials with special laminates or coatings can be used to create a barrier that is difficult for children to breach.


4.    Adhesive Technologies:
-  High-Strength Adhesives: Using strong adhesives for sealing blister packs can increase the effort required to open them.
-  Adhesive Bonding Techniques: Employing advanced bonding techniques to seal the blister pack can enhance its child-resistant properties.

The choice of method often depends on factors such as the type of product, the target audience, and regulatory requirements.

For child-resistant packaging, the methods mentioned are general industry practices, and specific machinery or equipment used for creating child-resistant blister packaging could vary.

It's important to note that the design and implementation of child-resistant blister packaging should comply with local regulations and standards.
