KEY FACTORS TO CONSIDER IN CHOOSING BLISTER PACKAGING Types:Product Protection: Products requiring higher security and protection typically benefit from full-face or trapped blister designs.Consumer Access: Slide blisters allow for easy opening and resealing, while face-seal or clamshell blisters provide a tamper-evident seal.Cost and Sustainability:Traditional blister packs may be cheaper but use more plastic. Newer, eco-friendly blister packs can reduce plastic use and appeal to eco-conscious consumers.TYPES OF SEALING USED IN PACKAGINGWhen it comes to sealing packaging made of paper and board, several methods are commonly used to ensure secure closures while maintaining the integrity of the materials. Here are some types of sealing methods specifically applicable to paper and board packaging:Adhesive Sealing This method involves applying an adhesive to bond the edges or flaps of paper or board packaging. It can include water-based, solvent-based, or hot-melt adhesives, which are commonly used for cartons, boxes, and envelopes.Tape SealingAdhesive tape, such as packing tape or gummed tape, is used to seal boxes and cartons. This method is widely used for shipping and distribution, providing a quick and effective closure.Stitching or StaplingThis involves using metal staples or stitching to secure the edges of paper bags or boxes. It%u2019s often used for heavier items or when added strength is needed.Pressure SealingSimilar to adhesive sealing, pressure sealing uses pressure to bond the edges of paper or board packaging, often in conjunction with adhesives or coatings.Heat-SealingWhile less common with paper and board compared to plastic, some hybrid materials (e.g., paper coated with a heat-sensitive layer) can be sealed using heat-sealing methods. This is often used for flexible packaging that combines paper with plastic.Die-Cutting and Locking TabsSome paper and board packages incorporate die-cutting and locking tabs that fit into each other to secure the package without the need for adhesives. This is common in some types of boxes and display cartons.Glued SeamsMany cartons and boxes feature glued seams where the flaps are bonded together using adhesives, providing a strong and secure seal.Window SealingIn some packaging designs, transparent films are used as windows that can be sealed to the paper or board using adhesives or heat sealing.Kraft Paper TapeThis eco-friendly option is used for sealing packages, especially in shipping and retail applications, providing a secure closure while being recyclable.Each sealing method has its own advantages and is selected based on factors like the type of product, required strength, ease of opening, and sustainability considerations.42
