Cosmetic manufacturers producing under-eye treatments need efficient packaging solutions. In “eye mask pack” production, a specialized blister packaging machine can form, fill, and seal each individual mask pack with precision and speed. These machines use rolled plastic film (PET or PVC) to thermoform cavities, dispense measured serum or gel, apply a foil or film lid, and then punch out sealed blister cards. The result is a hygienically sealed pack that protects delicate gel mask formulas from contamination and spoilage. For details on these advantages, see the Benefits of Blister Packaging for Eye Mask Packs section below.
Benefits of Blister Packaging for Eye Mask Packs
Blister packaging offers key advantages for single-use eye masks. It creates an airtight, tamper-evident seal around each mask, preserving sensitive ingredients and ensuring hygiene. Each patch is individually sealed until opened, preventing cross-contamination. Manufacturers also benefit from precise portioning: machine-metered fills guarantee a consistent dose for each application, reducing waste. A few of the main benefits include:
Protection & Freshness: Blister packs shield eye mask products from air, moisture, and light. This extends shelf life of active serums (e.g. antioxidants or hyaluronic acid in a hydrogel patch) so ingredients remain potent until use.
Hygienic Single-Use: Each eye mask (for puffiness or dark circles) is sealed separately, ensuring a fresh, sterile product every time. The foil or film backing is tamper-evident, so any breach is immediately obvious.
Precise Dosing: Automated filling pumps deliver the exact amount of gel or solution into every blister. This portion control means less waste of expensive active ingredients and consistent results for end-users.
Premium Presentation: Clear blisters showcase the eye mask product (e.g. gold leaf-infused or gel patches) and allow for colorful branding on the backing card. This premium look helps high-end items (like Sarah Chapman Eye Masks or Wander Beauty patches) stand out on shelves.
Efficient Production: Machines run continuously, producing hundreds or thousands of packs per hour. For example, advanced eye mask blister machines operate at 20–40 cycles per minute (roughly 1,300–4,000 packs/hour, depending on configuration). This is far faster than manual pouch packing, enabling scalable production.
Collectively, these benefits make blister packaging ideal for under-eye cosmetic products. By ensuring each mask remains sealed and uniform, manufacturers build consumer trust and reduce recalls.
How Blister Packaging Machines Work for Eye Masks
Blister packaging machines perform a sequence of steps to create each eye mask pack. They typically combine forming, filling, sealing, and cutting stations in-line. The core process is: form cavities, fill with product, seal with lid film, then punch out packs. A typical cycle includes:
Forming Cavities: Roll-fed plastic film (commonly PET or PVC) is heated and thermoformed into shallow blister pockets. For example, heated PET sheets are pushed into molds by air pressure, creating custom-shaped wells for the eye masks.
Material Filling: The formed web indexes forward to the filling station. For eye masks, precision pumps inject gel or liquid serum into each cavity. High-end machines use servo-driven pumps with feedback control, delivering consistent fill weights (often accurate to ±0.1g).
Cooling/Setting: Many hydrogel eye masks require the gel to cool or set in place before sealing. A chilled plate or cooling tunnel (sometimes ~ –25°C) quickly solidifies the fill, preventing leakage and shortening cycle time.
Sealing: Once filled, a lidding material (aluminum or plastic foil) is fed on top of the cavities. The machine seals the lid over the blister pockets using heat and pressure. This creates an airtight package for each mask.
Punching/Cutting: Finally, the sealed web is indexed to a cutting station. Blister cards or strips are die-cut or perforated into individual packs. Excess web scrap is trimmed or wound off. The finished eye mask packs emerge ready for boxing or further packaging.
These steps are integrated on a single line, often with in-line quality checks. Built-in sensors and cameras inspect fill levels and seal integrity, automatically rejecting any defective blisters. For example, a sensor can detect an underfilled cavity before sealing. Advanced machines may also emboss batch codes or use vision systems to align print on the packaging.
Key variations include rotary versus platen machines. Platen (intermittent) machines clamp and seal one index at a time, while rotary (continuous) machines form and fill on moving drums for higher speeds. Both types follow the same forming–filling–sealing–cutting process described above.
Blister Packaging Process Highlights
Materials: Most eye mask blisters use PET film for its clarity and rigidity. The machine should handle your film thickness (typically 0.1–0.7mm) and seal it to the chosen lid foil. PET is recyclable and often preferred over PVC. Some machines also accept aluminum foil for cold-form packs (better barrier but slower process).
Automation: Modern machines are PLC-controlled with servo drives. They include automatic web tracking and self-centering molds for precise alignment. Digital touchscreens and recipes allow quick changeovers between pack sizes.
Filling Options: Depending on the product, machines can handle single- or multi-color fills (enabling bi-layer gels or multi-ingredient formulas). Some machines have multi-channel pumps to fill several cavities simultaneously.
Sealing Technology: Plate-sealing is common (ideal for aluminum foil lids), while roller-sealing can run continuously with plastic films for higher throughput. Optional lid preheating can improve seals on tricky materials.
Throughput: Check both cycle rate and cavities per cycle. For example, a machine with 3 blisters per cycle at 20 cycles/min yields ~3,600 packs/hour. Higher-cavity molds (6 or more) can push output over 10,000 packs/hour on fast machines.
Key Features & Buying Tips for Eye Mask Packaging Machines
When selecting a blister machine for eye mask packs, consider the following factors:
Speed & Capacity: Match machine output to your volume needs. High-end models reach 20–40 cycles/min (over 1,000 blisters/min in some designs). Consider how many cavities (masks) you need per blister (1, 3, 6, etc.), as this multiplies throughput.
Filling Precision: Look for precise pumps. Accuracy of ±0.1g or better is standard for cosmetic fillers. Better precision reduces product giveaway of expensive serums.
Material Compatibility: Ensure the machine supports your chosen materials. Confirm it can handle your blister film (PET, PVC, or foil) and lidding (aluminum foil or peelable laminates). PET is eco-friendlier than PVC. The right clamping and heater settings are needed for different thicknesses.
Flexibility & Changeovers: Eye mask sizes/shapes vary. A machine should allow easy mold changes. Quick-release molds and adjustable tooling simplify switching between products (e.g. from a 2-mask blister to a single-mask design).
Automation & Controls: Advanced PLC/HMI controls are critical. Features like automatic film tracking, missing-piece detectors, and recipe storage improve reliability. A touchscreen interface speeds up setup.
Quality & Hygiene: Machines should be stainless steel (food-grade finish) for easy cleaning. Check for features like CIP (clean-in-place) systems or smooth designs. Line integration for CIP and clean utilities is a plus.
After-Sales Support: Choose reputable suppliers with strong service networks. The machine is a long-term investment—look for training, spare parts availability, and warranty. Reputable vendors often have local agents in major markets (U.S., U.K., Australia).
Cost vs. ROI: While capital cost matters, factor in efficiency gains. Automated blister packing greatly reduces labor and error compared to manual capping or pouching. Estimate payback by saved product (from accuracy) and increased throughput.
Selecting the right machine means balancing current needs with future growth. For example, buying slightly above current volume can accommodate product line expansion. Always compare specs (speed, footprint, power consumption) and read case studies.

Popular Eye Mask Products
Manufacturers often design blister machines around specific eye mask products. Below are examples of product categories and related search terms:
Hydrogel Under-Eye Patches: Many top-rated serums (often labeled “best under eye mask” or “best under eye patches for puffiness”) are gold or jelly-like gel pads packaged in blisters. Each pair is vacuum-formed into a cavity and foil-sealed to preserve nutrients.
Brightening Dark-Circle Masks: Gel patches with ingredients targeting dark circles (search term “best eye masks for dark circles”) are filled with brightening serums. Blister sealing keeps the active formulas intact until use.
Designer Brand Patches: Premium lines like Sarah Chapman Eye Masks or Wander Beauty Under-Eye Masks come in individually blister-packed form to highlight their luxury formulas. For example, Wander’s gold-infused patches (Baggage Claim) are displayed in transparent blisters to showcase the product.
Cooling Gel Pads (Ice Pack for Eyes): Eye pads designed like mini ice packs (for puffiness relief) often contain cooling gel. These are typically pre-loaded in sealed blisters or film pouches to maintain hygiene and prevent leaks.
Self-Heating Masks: Products such as Spacemasks Self-Heating Eye Mask (5-pack) are disposable warming masks. While sold as multi-packs, manufacturers can blister-seal individual masks to lock in heat-activating ingredients until open.
Under-Eye Pads: (Search term “best under eye pads”). These are another form of gel patches. They follow the same blister-filling process as under-eye masks.
Sleep/“Blackout” Masks: (Search term “blackout mask”). These cloth or foam sleep masks are not filled products, so they’re usually folded and packed in boxes or pouches rather than blisters. Blister machines are for fluid/gel products, not fabric masks.
