Pro-Pak Associates engineers and supplies custom clamshell and blister packaging for product companies, engineers and purchasing teams. Since 1996, we have helped customers design and deliver thermoformed packaging that protects their product, shows it off and holds up from the production line to the retail shelf.
Both are thermoformed plastic packaging: a sheet of plastic is heated, formed to a three-dimensional shape, then trimmed and finished. A blister is a formed cavity, either generic or custom designed around your product, that is typically sealed to a printed card. A clamshell is a hinged, two-sided package that closes around the product. Both offer tamper-evident protection that a plain printed box cannot.
Tell us about your product and we will recommend the right package, material and approach.
