PVC is known for its rigidity and affordability, while PET offers superior clarity and strength. PETG combines the benefits of PET with enhanced durability, making it suitable for more demanding applications.
The design phase is crucial in clamshell blister packaging production. It involves creating a package that not only secures the product but also enhances its visual appeal. Designers use advanced CAD (Computer-Aided Design) software to develop precise molds that accommodate the product's dimensions and protect it during transportation and display.
Ergonomics and user experience are also considered to ensure ease of opening while maintaining tamper evidence. Incorporating features like hang tabs or stand-up bases can improve shelf presence. Collaborating with a reputable clamshell blister packaging provider can enhance the design process through expert insights and innovative solutions.
Customization allows brands to stand out in a competitive market. By tailoring the shape, size, and features of the packaging, companies can create a unique identity. Embossing logos or incorporating custom colors can strengthen brand recognition. Additionally, the inclusion of inserts or backing cards provides space for branding and product information.
Thermoforming is at the heart of clamshell blister packaging production. This process involves heating plastic sheets to a pliable forming temperature, then molding them to a specific shape in a mold, and trimming to create the final product. There are two primary thermoforming methods: vacuum forming and pressure forming.
Vacuum forming uses a vacuum to draw the heated plastic sheet against the mold surface. This method is ideal for simple designs and is cost-effective for large production runs. Vacuum forming provides adequate detail and is suitable for packaging items that do not require intricate molding.
Pressure forming involves applying positive air pressure on the heated plastic sheet against the mold, allowing for higher detail and sharper edges compared to vacuum forming. This method is used for complex designs where aesthetics and precision are paramount.
After thermoforming, the molded plastic requires cutting and trimming to achieve the final shape. This step utilizes precision cutting equipment, such as steel rule dies or CNC routers, to remove excess material and ensure uniformity. Accurate trimming is essential for the clamshell halves to align correctly, ensuring the packaging functions as intended.
Advancements in cutting technology have improved efficiency and reduced waste. Techniques like laser cutting provide high precision and can handle intricate designs, contributing to the overall quality of the packaging.
A defining feature of clamshell packaging is the hinge connecting the two halves. Hinges can be living hinges molded into the plastic or mechanical hinges added during assembly. The choice depends on factors such as material, design complexity, and intended use.
Closure mechanisms vary from simple friction fits to more secure snap closures. Some designs incorporate tamper-evident features to enhance product security. The development of these components requires careful engineering to balance ease of use with protection.

Techniques such as incorporating adhesive strips or interlocking tabs enhance functionality. Collaboration with a blister box packaging specialist can yield creative solutions tailored to specific products.
While the clamshell itself is clear, printing and labeling play a significant role in conveying information and branding. Backing cards inserted into the packaging provide space for graphics, instructions, and regulatory compliance information. High-quality printing techniques ensure vibrant colors and sharp images that attract consumer attention.
In some cases, the plastic itself can be printed using specialized inks and processes. This direct printing can create a seamless look but requires careful selection of inks compatible with the plastic material.
Packaging must comply with industry regulations, including displaying necessary product information, safety warnings, and barcodes. Working with experienced manufacturers ensures that all compliance requirements are met without compromising design aesthetics.
The final assembly involves sealing the clamshell to secure the product. There are several methods, including heat sealing, ultrasonic welding, and RF (Radio Frequency) sealing. The choice depends on the materials used and the desired strength of the seal.
Heat sealing is common for materials like PVC and PET and provides a tamper-evident closure. Ultrasonic welding uses high-frequency vibrations to bond the plastic, suitable for more rigid materials. RF sealing is effective for detailed and complex shapes, offering a clean finish.
An alternative to clamshell packaging is face seal blister packaging, where the plastic blister is sealed to a cardboard backing. This method is cost-effective and allows for extensive graphic design on the backing card. The sealing process is similar, utilizing heat or adhesives to bond the materials.
Ensuring the quality of clamshell blister packaging is critical. Manufacturers implement rigorous quality control procedures, including dimensional inspections, material testing, and functional assessments. These measures verify that the packaging meets design specifications and will perform effectively in real-world conditions.
Testing may involve checking the seal strength, hinge durability, and resistance to environmental factors like temperature and humidity. Quality management systems, such as ISO certifications, help maintain high standards throughout production.
Packaging for certain products, like food and pharmaceuticals, must comply with specific regulatory standards.
