Custom clamshell packaging is the perfect option for thousands of products. At Indepak, we can create virtually any size or shape of clamshell that you might need. Throughout the past 50 years, we have created clamshells and other types of custom packaging for many different industries. Here’s a quick look at our production process and the services we offer.

Quality Design

Our team of expert designers will work with you every step of the way to ensure that your custom clamshell packaging fits your needs and budget. During the design process, we pay attention to many factors, including weight, strength, presentation and cost-containment to find the best possible packaging solution for each client. We will provide you with initial designs as well as a prototype before we begin the production process.

Fast Production

Our facility includes multiple lines of high-speed thermoforming equipment. This variety of equipment allows us to meet the needs of many clients as quickly as possible. Our equipment is able to process rigid materials from .008” to .080” in thickness and foam materials from 1/16” up to ¼”. Our equipment also is capable of creating quality custom clamshell packaging, blister packaging, thermoform trays, parts and more.


Sustainability is something we take very seriously at Indepak. Our facility is located in Portland, a city known for its environmental innovation, and we’ve been reducing, reusing and recycling for decades, long before it was popular or required. We offer our clients many different sustainable options for their custom clamshell packaging and blister packaging.

Our equipment is able to process a myriad of thermoform plastic materials, including PET, PETG, HDPE, ABS, PVC, PP and OPS. Nearly all of the materials we use are recyclable, and we also can use starch-based biomaterials for many custom clamshell packaging designs. Our innovative design team can create packaging that incorporates a combination of plastic materials along with paper or pulp. We also can use post-consumer grade materials for your packaging. Additionally, our design team works diligently to reduce the overall amount of packaging needed to protect and display your product, reducing waste and reducing your costs.

Additional Services

In order to provide a total solution for each of our clients, we provide several additional services. For instance, we offer package fulfilment services and we can seal your custom clamshell packaging together using processes such as heat sealing or perhaps RF welding. Our facility also includes 50,000 square feet of warehouse space, and we can create a personalized inventory management just for you, ranging from simple minimum/maximum systems to customer-based web portals.

Since 1967, Indepak has a been a leading producer of quality packaging for many industries, including the specialty foods industry, the medical & pharmaceutical industry, the electronics industry, the agricultural industry and for a myriad of retail products. Whether you need custom clamshell packaging or another type of thermoform plastic packaging, the team at Indepak is equal to the task.
