How Do Strip Packaging Machines Compare to Blister Packaging Machines?
Strip packaging machines and blister packaging machines serve distinct purposes, with differences focused on their structural and operational packaging differences. Products that need to be packaged using strip packaging methods are sealed between two layers of foil or film, which is suitable for most moisture sensitive products, especially medicines. On the other hand, the blister packaging cavity is created out of durable plastic and sealed with a backing, which works perfectly for consumer goods as it makes the package tamper-proof as well as eye-catching. While strip packaging is great for single-use unit doses, blister packages can have more visual marketing, making them more appealing for retail settings. Both options serve specific requirements but, in the end, are modified to achieve expected product parameters and usage.
Differences in Packaging Process and Materials
The approaches and components used in strip and blister packaging are worlds apart from each other. Strip packaging processes begin by placing items between two films made of foil or coating plastic. The films are then heated under a certain amount of pressure to create units. This method protects sensitive items from moisture and other environmental conditions, making it ideal for easily damaged items. In contrast, a cavity or pocket is formed in the sheet of foil or plastic in blister pack, and the product is attached to the sheet with a corresponding lidding material. Cavity formation is achieved through a thermoforming or cold forming process. The materials selected for blister packs also ensure product safety and visibility, thus protecting them from tampering whilst making retail promotional display easy. The precision in selection for the materials and sealing technologies for the packaged items is what makes both formats unique.
Judging Efficiency and Output Parameters
When considering efficiency and output parameters, the performance of strip packaging tends to be more efficient than blister packaging when it comes to high volume production speed. Strip packaging machines have less frequent interruptions such as pauses or breaks and are therefore often constructed to run non-stop, increasing throughput. However, blister packaging is much more flexible with regards to customization in shape, size, tamper evidence features, and product visibility, which may set production speed back based on the complexity of the design. Moreover, the precision that is required during the thermoforming and cold-forming stages in blister packaging can slightly decelerate the process due to material handling. Ultimately, the selection between the two boils down to product protection, presentation, and company’s intention in manufacturing.
When to Use Strip Vs. Blister Packaging
As for the airtight sealing and protection from elements like moisture, light, or oxygen, strip packing is appropriate. It is most suitable for unit-dosed tablets and capsules. The continuous sealing mechanism in strip packaging ensures superior hermetic integrity without relying on complex thermoforming processes, making it a preferred choice for sensitive pharmaceuticals.
Blister packaging, however, works well for products which need to be seen, where branding is valuable, and where tampering is suspected. Its design offset areas can be made to unique shapes and sizes, making it suitable for a variety of products, including medical devices, consumables, and food. Blister packaging is particularly proficient at providing mechanical protection during the transport and handling of a product while also enabling easy dispensing of the product.
From a technical perspective, strip packaging is effective when there is a need for light seal strength and simplicity instead of speed, as it works on average 120-160 packs per minute. Blister packaging machines are more versatile; they typically process 80 to 150 cycles per minute depending on features such as the cavity design, the type of material used, lids, and whether the package is perforated. Material selection also plays a vital role; strip packaging primarily uses aluminum foils for barrier properties, while blister packaging combines PVC, PVDC, or aluminum laminated materials for durability and presentation.
To select the best method requires identifying the balance that can be struck between how efficient the process is, what the product demands, and how environmentally friendly or promotional the exercise needs to be. For example, strip packaging is relatively simple but provides less scope for brand identification compared to blister packaging, which provides the necessary custom branding but at the chutney of production speed.
