Medical Blister Trays and Lidding
Thermoformed medical trays and compatible lidding materials for sterile medical device packaging projects, coordinated according to device geometry, protection requirements, sealing process and sterilization method.
Medical Blister Tray Packaging Overview
Medical blister trays and lidding are commonly used to protect medical devices that require secure positioning, physical protection and controlled presentation within a packaging system. The thermoformed tray provides a shaped cavity for the device, while the lidding material is sealed to the tray flange to form the package closure.
Depending on the project, tray materials may include PETG, APET, PVC or other thermoformable medical packaging materials. Lidding options may include coated Tyvek®, medical-grade paper or other compatible materials selected according to the tray substrate, sealing process, sterilization method and required opening performance.
Medical blister trays and lidding must be evaluated as a complete packaging system. Tray geometry, flange design, material thickness, lid coating, sealing parameters, device weight and distribution conditions can all affect package performance.
Jinhong Packaging coordinates medical tray and lidding projects with selected manufacturing partners. We help customers compare material options, confirm technical requirements, review drawings and organize samples or supporting documents for further packaging evaluation.

Medical Tray and Lidding Options
The appropriate configuration depends on the medical device, required cavity design, sterilization process, opening method and validation plan. The following options can be coordinated according to project requirements.
Thermoformed Medical Trays
Rigid or semi-rigid thermoformed trays designed to hold medical devices in a defined position and help protect them from movement, impact or compression during handling and distribution.
Tray dimensions, cavity depth, flange width, wall thickness and device-retention features can be developed according to the device drawing or physical sample.
Tyvek® Lidding
Coated Tyvek® lidstock can provide microbial barrier performance, strength and clean-peel opening for compatible tray systems.
The Tyvek® grade, coating system, tray material and sealing parameters must be selected and evaluated together. Compatibility with the intended sterilization process must also be confirmed for the complete package.
Medical-Grade Paper Lidding
Medical-grade paper lidding may be considered for selected tray systems where porosity, printability and peel performance are required.
Paper basis weight, coating type, seal compatibility and sterilization requirements should be confirmed according to the specific application. Medical-grade paper is not automatically suitable for every tray material or sterilization method.
Materials and Package Structure
Material selection for medical blister trays and lidding should begin with the medical device and the intended packaging process. Device geometry, weight, sharp edges, required visibility, sterilization method, sealing equipment and distribution environment can all influence the final package structure.
Thermoformed Tray Materials
Thermoformed medical trays may use PETG, APET, PVC or other project-specific materials. Each material has different forming, clarity, rigidity, sealing and processing characteristics.
PETG is frequently considered for clear thermoformed medical trays because it can support detailed cavity designs and product visibility. APET may be evaluated where clarity, rigidity or material efficiency is important. PVC remains available for certain established applications, subject to customer, market and regulatory requirements.
The final material should be confirmed according to the tray design, device characteristics, lidding system, sterilization process and required package validation. Material availability may also vary by thickness, order quantity and manufacturing partner.
Lidding and Heat-Seal Coatings
Lidding materials may include coated Tyvek®, medical-grade paper or other compatible porous and nonporous structures. The heat-seal coating creates the bonding interface between the lid and the tray flange.
A suitable lidding system must provide the required seal strength while supporting controlled opening and acceptable peel characteristics. Excessive seal strength may make the package difficult to open, while insufficient or inconsistent sealing may affect package integrity.
Lidstock grade, coating weight, tray substrate, flange condition, sealing temperature, pressure and dwell time should therefore be evaluated as part of the complete sealing process.
Tray material, flange design, lidding grade and heat-seal coating must work together to achieve the required sealing and opening performance.

Applications and Selection Considerations
Medical blister trays and lidding can be developed for a wide range of medical devices that require defined positioning, product visibility or additional physical protection. The packaging configuration should be selected according to the device and its complete use environment rather than by tray appearance alone.
For a step-by-step material, cavity, lidding and purchasing checklist, read our medical blister tray and lidding selection guide.
1. Surgical and Procedural Devices
Thermoformed trays may be used for selected surgical instruments, procedural components, device kits and accessories that require organized presentation and protection during handling.
2. Catheters and Diagnostic Components
Custom cavities and retention features can help position catheters, diagnostic components and related accessories while reducing unnecessary movement inside the package.
3. Implants and Sensitive Devices
Rigid or semi-rigid tray systems may be considered for implants and sensitive medical devices where dimensional stability, physical protection and controlled presentation are important.
4. Medical Device Kits
Multi-cavity trays can organize several components within one package. Component arrangement, accessibility and the intended opening sequence should be reviewed during tray development.
What Should Be Confirmed Before Material Selection?
Before selecting a tray and lidding combination, the project should define the device dimensions, weight, geometry and any sharp or delicate areas. The required cavity depth, retention method, flange width and peel direction should also be considered.
The intended sterilization method is another key factor. A material that performs well during thermoforming or sealing is not automatically suitable for every sterilization process. Tray material, lidstock, heat-seal coating, printing system and device characteristics must be reviewed together.
Packaging evaluation may also need to consider seal strength, visual seal quality, package integrity, aging and distribution performance. The applicable tests and acceptance criteria should be determined by the medical device company according to its product, market and validation plan.
A successful tray project begins with the device—not with a standard material list. Providing a drawing, sample, sterilization method and packaging requirements at the beginning can reduce unnecessary material changes and repeated sampling.
Quality Documents and Project Coordination
Medical blister tray and lidding projects often require more than a product quotation. Device information, tray drawings, material specifications, sealing requirements, sterilization conditions and validation responsibilities should be clarified before the final package configuration is confirmed.
Depending on the selected manufacturing partner and material system, available documentation may include material specifications, certificates of analysis, declarations of conformity, quality management certificates, inspection records and relevant test reports. Document availability and applicability must be confirmed for each project rather than assumed to cover every product configuration.
ISO 11607-1 addresses requirements for materials, sterile barrier systems and packaging systems for terminally sterilized medical devices. ISO 11607-2 addresses validation requirements for forming, sealing and assembly processes. ASTM F88/F88M may be used to evaluate the strength of seals between flexible lidding and flexible, rigid or semi-rigid materials.
The medical device company remains responsible for determining the applicable regulatory requirements, establishing acceptance criteria and validating the final packaging system for the intended device, sterilization process, distribution environment and target market.
