Custom Thermoformed Plastic Packaging Solutions

Thermoformed plastic is a plastic sheet that is heated until pliable, formed over or into a mold, and trimmed into a finished shape. The process is commonly used to make trays, blister packs, clamshells, inserts, and protective product packaging. It enables packaging to be tailored to product dimensions while supporting visibility, handling, protection, and retail presentation requirements.

Thermoforming packaging is packaging made by heating a plastic sheet and shaping it with a mold into a specific form. Common examples include food trays, medical trays, retail clamshells, and blister packaging. A packaging project can be customized around product size, required rigidity, sealing needs, shelf appearance, production volume, and moisture or oxygen barrier specifications.

Thermoformed packaging works across many product categories, including food and beverage items, meat and poultry, medical devices, pharmaceutical and OTC products, electronics, cannabis products, and consumer goods. The best format depends on the product’s dimensions, fragility, sanitation needs, retail display goals, and distribution conditions. Trays, blisters, clamshells, and inserts each address different functional needs.

A tray is an open formed package or insert that cradles a product. A blister pack typically uses a formed plastic cavity paired with a paperboard or foil backing. A clamshell has hinged or matching formed halves that enclose the product. The appropriate choice depends on visibility, tamper resistance, product protection, sealing method, and how the package will be displayed or filled.

Yes. Packaging structures can be selected around needed oxygen and moisture barrier performance, often measured through OTR and WVTR requirements. These specifications are especially important for products sensitive to moisture, oxidation, aroma loss, or shelf-life changes. Providing product details, target shelf life, distribution conditions, and fill-line requirements helps identify a structure suited to the application.

Thermoformed packaging can be suitable for medical, pharmaceutical, OTC, and aseptic applications when the format, materials, and production controls match the product’s requirements. Formosa offers cleanroom-produced packaging capability, including Class 10,000 cleanroom capability. Brands should define product-contact needs, sterilization or cleanliness requirements, barrier needs, validation expectations, and applicable regulatory obligations early in development.

Sustainable packaging options may include recyclable or compostable structures selected according to product and sustainability requirements. Suitability depends on the product, required barrier performance, local end-of-life infrastructure, package design, and compatibility with existing equipment. A practical review considers whether the proposed material will protect the product and meet production needs while supporting the brand’s stated sustainability objectives.

Start with product dimensions, photos or samples, product weight, estimated quantities, intended market, desired package format, and any filling or sealing equipment details. It is also helpful to identify barrier targets, printing or finish needs, cleanroom requirements, sustainability goals, and target timing. These details allow the packaging team to match the project with the appropriate thermoforming capability and structure.
