Bao bì thẻ vỉ là gì? Hướng dẫn đầy đủ về dược phẩm & Công nghiệp bao bì

Thermoformed plastic blisters (as shown below) are commonly used to protect and display small products. These blisters are clear plastic trays formed with cavities (pockets) that hold individual items. The blister is typically sealed against a backing material—such as paperboard or aluminum foil—to enclose each product. This design not only visibly showcases the product but also protects it from moisture, dust and tampering. Ví dụ, the image below shows a medication blister card: a plastic film with molded pockets attached to a printed card. Each pocket (or “blister”) holds a tablet, and the card can be labeled with instructions or branding.

Nhân vật: A thermoformed plastic blister tray. Such blisters are molded from materials like PVC or PET and often sealed with a paperboard or foil backing.

Understanding Blister Card Packaging

Blister card packaging (also called a slide blister hoặc trap blister) combines a molded plastic blister with a rigid paperboard card. In this format, the plastic film forms cavities for the product, and a pre-printed card is attached as a backing or cover. The card provides space for branding, product information and instructions, and it can include features like hanging holes for retail display. In many designs, plastic flanges on three sides wrap around the card so it can slide securely into the blister. Once assembled, the card and blister form a tamper-evident package: the blister is heat-sealed to the card or held by clips, preventing removal of the product without visible damage to the pack. This packaging is popular in pharmaceuticals and retail because it combines product visibility with sturdy protection and merchandising appeal.

Blister packaging comes in several common types, each suited to different products and uses:

• Slide (Trap) Blister/Card Packaging: A plastic blister with three sealed sides and one open end. The card slides into the open side and is secured (often by staples or tape). No heat sealing of the card edges is needed. This type is exactly blister card packaging, and it allows the card to be customized and securely hold the blister.
• Face Seal Blister: The plastic blister and the card are sealed together along their perimeter by heat or adhesive. The blister cannot slide out; the consumer must peel or tear the seal to open. Face-seal blisters hold the product more permanently and are hard to open without damage.
• Clamshell Blister: A hinged “clamshell” plastic case (often transparent) that closes around the product. Clamshells have two identical halves that snap or heat-seal together. They are reusable and can be used without a separate card, though header cards can be added. Clamshells can be locked closed to deter theft.
• Blister Tray: A single plastic tray (mụn rộp) without a card. The tray can be placed inside another package or a printed box to complete the package. This is often used for food or hardware items.

Each type offers different levels of protection, trị giá, and convenience. Blister card and face-seal designs provide extra security (tamper evidence), while slide blister cards allow easy assembly and re-closure. Manufacturers choose the style based on product size, shelf-life needs, and branding requirements.

Vật liệu được sử dụng

Blister cavities are typically made from clear thermoformed plastics. Vật liệu phổ biến bao gồm PVC (polyvinyl clorua) Và THÚ CƯNG (polyethylene terephthalate) for good clarity and stiffness, Và PP (polypropylene) when higher heat resistance is needed. PVC-based films (with or without PVDC coating) are widely used because they form easily and clearly show the product. PET is more recyclable and has excellent transparency, while PP tolerates higher temperatures. For the lidding material, manufacturers often use Lá nhôm hoặc coated paperboard to seal the blister cavity. PVC/PET films are heat-sealed to foil to create a moisture- and oxygen-resistant package. (Cold-form aluminum laminate is also used in some pharmaceutical blisters for superior barrier properties.) Overall, material choices balance clarity, hiệu suất rào cản, và chi phí.

How Blister Card Packaging Machines Work

Specialized blister card packing machines automate the assembly of blister cards. These machines take the blister sheets (with products loaded in advance), pick and place the first card, position the blister, add a second card, and then heat-seal or clamp the layers together in one continuous process. One common workflow is: an automatic feeder supplies a cardboard backing, a plastic blister (with tablets or items inside) is placed on it, and then a top card is aligned and pressed in place. Heat or ultrasonic sealing units then bond the blister to both cards. Cuối cùng, the machine cuts or ejects the sealed blister-card units. Modern systems are fully servo-driven, achieving precise alignment (to within 0.1 mm) and synchronized motion. JinLupacking notes that our machines meet European/CGMP standards, ensuring each blister card is perfectly formed and sealed. These machines can handle high speeds (sealing thousands of cards per hour) and multiple size formats by changing molds and adjustment slides.

Benefits of Blister Card Packaging

Blister card packaging offers many advantages for pharmaceutical and retail products:

• Clear Product Visibility: The transparent blister lets customers see the actual product. This “window” display builds trust by showing the item inside. High-visibility packaging tends to attract attention on shelves.
• Tamper-Evident Security: Blister cards are sealed so that any attempt to open them leaves obvious damage. This is crucial for medicines and health products, where safety and integrity are paramount.
• Nhỏ gọn & Hiệu quả chi phí: Blister cards are lightweight and space-efficient, which can reduce shipping costs. They allow high-speed, high-volume production, making them economical for manufacturers.
• Branding Opportunities: The paper card provides a large printable area for logos, instructions, and marketing messages. Custom graphics and information can be added directly to the card, enhancing brand recognition and providing dosing or usage details at point of sale.
• Bảo vệ sản phẩm: The sturdy card and sealed blister protect contents from moisture, bụi, and breakage during transport. Each unit is individually enclosed, preventing cross-contamination or loss of small items.
• Tiện lợi người tiêu dùng: For unit-dose medications, blister cards can be organized by day or dosage, helping patients follow their regimen. The image below is a medication blister card that organizes doses by time of day, illustrating how blister cards can improve patient compliance.

Nhân vật: An example of medication blister cards (unit-dose packaging) used to organize daily doses. Each pill is sealed in a blister cavity attached to a labeled cardboard sheet.

These benefits make blister card packs extremely popular for pharmaceuticals (máy tính bảng, viên nang, Vitamin) và hàng tiêu dùng nhỏ (electronics accessories, tools, Mỹ phẩm, vân vân.). By offering visibility, protection and branding in one package, blister card packaging is a versatile solution across many industries.

Applications in Pharma & Ngành công nghiệp

Trong ngành dược phẩm, blister card packaging is a standard for tablets and capsules. Unit-dose blisters help ensure accurate dosing and drug integrity. They are widely used for prescription drugs, over-the-counter medicines, và vitamin, often in multi-dose calendars or prescription-packed cards. Because each dose is sealed, patient compliance can be tracked (torn blisters indicate pills taken). The tamper-evident nature also supports regulatory requirements for drug safety.

Beyond pharma, blister cards are used for products like batteries, earbuds, hardware parts, Mỹ phẩm, và hơn thế nữa. Ví dụ, electronics or toy accessories often come in Gói vỉ hanging from retail displays. The rigid card holds the plastic blister and provides hook or slot options for merchandising. In automotive or hardware, small parts (fuses, ốc vít, fuses) are sold in blister card packs to keep them organized and visible. Trong mỗi trường hợp, the packaging both markets the product and protects it in transit.

Blister card packaging is ideal whenever a high-security, shelf-ready package is needed for small items. It offers traceability (via printed lot numbers on cards), child-resistance (with peel-tear seals), and can be made compliant with global GMP and FDA standards. Leading machine manufacturers (like Jinlu Packaging) design blister card solutions to meet these strict pharma and retail demands, enabling stable high-volume output and consistent quality.
