Packaging for Pharmaceutical
and Medical Products
Multilayer barrier resistant to moisture, oxygen, and microorganisms – a reliable solution for sterile packaging. When health is in the package, every layer serves to protect.
Higher resistance to water vapor permeability
Increased resistance to microorganisms
Packaging for Pharmaceutical and Medical Products
Continuous innovation in pharmaceutical and medical technology raises the bar for packaging solutions as well. Modern materials must seamlessly combine water vapor impermeability—to prevent moisture that accelerates hydrolysis and degradation of active substances—and high resistance to microorganisms, since even the slightest contamination is unacceptable in therapeutic or sterile use.
For unit-dose packaging of solid forms—such as tablets, capsules, and film-coated tablets—multilayer aluminum foils, PET/PE, and PET/PP laminates create a barrier that blocks oxygen, moisture, and UV radiation, while ensuring absolute hygienic separation of each dose. This maintains the declared potency and prevents the “transfer” of odor or moisture between adjacent units.
For medical disposables and surgical instruments (compresses, catheters, surgical sets), paper/PE or PET/PE structures are used, designed for gamma, EO, or steam sterilization. After terminal sterilization, microporous or peel-layer structures prevent microbial ingress, while the “easy-peel” design allows for aseptic opening with no fiber or film residue on the sterile contents.
The result is a pharmaceutical or medical product that reaches the user sterile, stable, and completely safe—exactly as it left the production line, protecting your brand, reputation, and the health of the end patient.

Barrier solutions for sterile and hygienic packaging of pharmaceutical and medical products
Packaging for Pharmaceutical and Medical Products – Reliability, Sterility, and Safety
Packaging for pharmaceutical and medical products must meet specific quality criteria due to its direct impact on the efficacy and safety of the final product. Such packaging protects products from moisture, oxygen, microorganisms, and other external factors, ensuring sterility and preserving the quality of substances during storage, transport, and use.
The following sections detail key aspects of packaging production, types of products requiring this packaging, specific materials used, and common technical features that ensure quality, safety, and reliability for the pharmaceutical and medical industry.
Production Specifics
Pharmaceutical and medical packaging is produced using specialized lamination and coextrusion processes, with strict hygiene and quality control in accordance with standards. These processes prevent contamination and provide a complete barrier against moisture and microorganisms.
Materials such as PET, PP, and PE are used in production. PET/PP structures are laminated with special solvent-free adhesives, resistant to gamma sterilization, and provide extremely reliable seals. PET/PE combinations are particularly suitable for easy-peel applications, while Paper/PE materials are plasma-treated for enhanced sterility and thermoforming capabilities.
Special attention is given to residual oxygen, moisture, and other substances in the packaging, which is critical for maintaining stability and efficacy, especially for probiotics and drugs requiring a controlled atmosphere.
Product Categories and Packaging Specifics
Packaging for pharmaceutical and medical products includes several specific categories:
Solid Oral Forms (tablets, capsules, lozenges)
These products require high protection against moisture and oxygen, typically using PET/PE structures with gamma sterilization and inert gas filling.
Semi-Solid/Topical Products (ointments, gels, patches)
Due to the need for high sterility and maintaining the integrity of ointments and gels, PET/PP laminates allow steam sterilization and provide excellent barrier protection for fatty components.
Sanitary Materials (gauze, catheters, syringes)
Paper/PE-based packaging is used for easy ethylene oxide (EtO) sterilization, high thermoforming capability, and aseptic easy-opening functionality.
Sterile Diagnostic Kits (reagent bags, rapid tests)
These kits require extremely high barrier protection (PET/AL/PE structures) to prevent contamination and are usually sterilized by gamma radiation or EtO gas.
Material-Specific Packaging Features
PET / PE
Characterized by good moisture and microbial barrier properties, moderate oxygen resistance, and easy opening capability. Suitable for standard oral packaging such as strip packs for tablets or capsules.
PET / PP
This combination offers high resistance to fatty components, is ideal for steam sterilization, and provides good microbial barrier protection. It is especially suitable for topical products, ointments, and sterile gels in sachet form.
Paper / PE
Allows excellent thermoforming, easy and aseptic opening, primarily used for sanitary materials and medical instruments requiring EtO sterilization. Limited barrier properties against fats.
Common Technological Features
Sterilization Without Barrier Loss
The materials maintain integrity after various sterilization methods: gamma radiation up to 25 kGy, ethylene oxide, or steam sterilization at 121°C.
Hermetic Seals with Easy-Peel Function
The packaging features strong yet easily peelable seals, ensuring controlled sterility of the contents until the moment of use.
Excellent Thermoformability
Materials such as Paper/PE and PET/PP are suitable for thermoforming into various packaging shapes without risk of material structure damage.
Stability in Vacuum and Inert Gas
The packaging is compatible with vacuum or inert gas filling, maintaining content stability with minimal residual moisture and oxygen, thereby extending product shelf life.
By selecting modern multilayer packaging tailored to the specific requirements of pharmaceutical and medical products, you ensure sterility, stability, and safety of every product from packaging to application – precisely in accordance with the highest quality standards.
