What is Blister Packaging:

There are several different kinds of premade transparent plastic cavities used for packaging small consumer products, meals, and medications, all of which go by the name “blister packing” or “Blister Pack.”  Likewise, Blister packs are comprised of a transparent plastic cavity or pocket and a covering, typically a paperboard card.

Customers provide a product that needs packaging (or submit a sketch of the idea), and a mould is made to create the packaging cavity. Typically, transparent PVC or PET plastic is used for the plastic gap. At this point, the plastic is either suctioned into or moulded over an aluminium mould while still hot.

Ordinarily, the plastic blister has a paperboard, lidding seal foil, or plastic covering affixed to it. Moreover, there is a window cut out of the backdrop or card allowing the product’s visuals and description to shine through and catch the buyer’s eye. Blister packaging with a hanging hole at the top is a convenient way to display products. These are often used in the pharmaceutical industry, where they are known as blister packs or blister trays.

Surprisingly, Blister packaging is a win-win for both merchants’ bottom lines and shoppers’ wallets thanks to its cost-effectiveness. A clear plastic container allows for a close visual inspection of the goods. In most cases, the rear card is bright and draws attention to the benefits of the product sandwiched between the blister packaging giving it a unique look.

Blister cards have an adhesive (a heat sealant layer) that is activated when heat and pressure are applied to the blister tray and card.  Cheery on top, The glue is robust enough to allow the item to be hung from a peg, yet it is still readily removed after the package is hung.

To facilitate the customer’s ability to inspect the object without risking the product’s safety, some cards containing bulkier products have a tiny window.

What is Clamshell Packaging:

Blister packaging comes in many forms, and clamshell packing (also known as clam packaging or clam packs) is one of them. Bulk Clamshell packaging, in contrast to standard blister packs, does not have a cardboard backing. As an alternative, it features a plastic rear that hinges to the front of the box at the side or the bottom. Some models have a hole that allows them to be displayed on pegboards, whereas others are designed to stand on their own on store shelves.

Sometimes they are heat-sealed, other times they feature a button to click shut. The size and form of the bubble might vary according to the item inside of it, or it can be the same dimensions and shape on the front and back.

Clamshell box packaging is convenient since it is simpler to use than other carded packaging options. plastic clamshell boxes have a similar appearance to their moniker, as they are constructed from two similar “shells” that are linked on one side and have little hinges to lock shut on the other.

Various polymers, including polystyrene, polyester, and PVC, are often used to make bulk clamshell containers. The material is malleable and may take the shape of a wide variety of objects thanks to thermoforming and injection moulding.

Although they aren’t as prevalent as plastic or metal clamshells, paperboard or paper pulp foldable cartons are also on the market right now. Styrofoam, cellulose, wheat, and paper generated from wood shavings are some of the other materials used to make clamshells.

You’ve probably seen clamshell packaging at a grocery store or on a food truck serving workers’ lunches. Salads, pre-made sandwiches, fruit, cupcakes, tiny mechanical things, and other commercial products are often wrapped in clamshells.

Due to their uniform construction from a single material, such as plastic or paper pulp, clamshells are an eco-friendly option. Despite the fact that clamshells often contain two different kinds of material, they nonetheless manage to make it through true reprocessing, even in single-stream recycling systems.

Difference Between Blister Packaging and Clamshell Packaging:

At bestpackaging100.com, we love working with thermoplastics and develop hundreds of blister packs and clamshells for our clients every year. These adaptable containers come in a broad range of sizes and forms, making them ideal for a wide range of products. Here are some details regarding these containers.

A plastic blister is different from a plastic clamshell in a few key respects, and knowing those distinctions might be useful initially.

1. Composition:

Plastics such as polyethene terephthalate (PET) or polyvinyl chloride (PVC) are used to create blister packs. Clear Blister packaging‘s durable construction makes them useful for several industries, including those involving drugs, electronics, and toys. The components of a plastic blister are a thermoform plastic cavity and a backing made of cardboard, foil, or plastic.

Many drug manufacturers also choose blister packaging made of plastic. All of us are familiar with the plastic blister packaging used to keep pills. There is usually a sturdy foil cover on the backside of this blister to avoid tampering. The plastic blister will be made in such a way that it not only keeps the drugs safe throughout transport but also prevents any humidity from lowering the quality of the medicines within.

However, If you’re looking for a container that looks like a clamshell, you’ll need to purchase a plastic clamshell. Clamshell packaging resembles clamshell a lot. It’s one solid piece that folds shut with a tab, snap or glue. A plastic clamshell resembles a blister pack in that it is only a blister pack that folds on top of itself, technically speaking.

 The composition of the clamshell is almost the same as the blister but bulk clamshell packaging is only composed of PET while blister packaging is made up of both PVC and PET.

2. Thermoforming:

Speaking of the thermoforming process, Thermoforming is the manufacturing technique responsible for the production of plastic blister packaging and clamshell wholesale packaging. Thermoforming is the process of softening a thermoplastic around a mould and then cooling it back to its original hard condition under a vacuum. It is safe to say that you can achieve any desired shape using blister or clamshell packaging since they are made through thermoforming.

The plastic transparent packaging clamshell is constructed from durable thermoplastic, making it ideal for stowing and transporting your goods. It’s safe to say that these two packaging kinds are among the most prominent on the market today.

3. Applications:

A custom plastic clamshell packaging is a kind of container having two movable halves that may shut together by folding over and latching onto each other along a central hinge. Many different things—from food to smartphones to electronics—are packaged in clamshells. As a general rule, more expensive products come in clamshell cases. It’s common for high-end golf balls to be sold in clamshell packaging, whereas low-cost domestic 9V batteries are often sold in blister packaging.

When it comes to packaging, many bakeries, grocery shops, and restaurants choose plastic clamshells. The plastic clamshells we’re talking about here usually only have a little tab or maybe an adhesive label to hold them shut.

While the plastic blister serves the same purpose, it does so in a somewhat different manner. Blister packs typically have a paperboard base and a thermoplastic window at the front. The paperboard and plastic blister has the same wide range of applications as the plastic clamshell. It’s multipurpose, so you can store everything from pencils and batteries to flash drives and toys to tools and shampoos.

4. Cost:

blisters packaging is a cheap solution but in some cases only:

Commonly seen on low-priced consumer goods, blister packs are a convenient and inexpensive packaging option. While an empty clamshell packaging box is typical for high-priced car parts, a blister package is more common for everyday items like tape measures.

The plastic clamshell, on the other hand, may have a more robust closure. Strong adhesive tapes or labels may be used to seal packages and prevent loss. A plastic clamshell, for instance, might be used to safely store a set of thumbtacks. A well-made label will protect the goods from tacks and provide you with important information about them.

In some cases, blisters are expensive because traditional blister packaging requires more costly machinery and labour to produce than a single carton. But if a lot of items need to be packed, those expenses may be divided across more items.

Comparatively, custom clamshell packaging containers are a common “off the shelf” option for packaging needs. Numerous manufacturers provide standardized moulds and dimensions. This reduces initial investment and, when used intelligently, maybe a very competitive choice.

5. Presence of Hinge:

In comparison to a clamshell, a blister doesn’t have a hinge, which is the primary distinguishing feature between the two. The term “blister” refers to the plastic or rubberized material used to secure a product to a paperboard card (header card). Because of their transparency, blister packs are ideal for displaying items.

6. Size Limitation:

Both Blister and clamshell packaging often have a few size limitations. The size restriction will be set by the equipment and tools available. It is possible to store almost any kind of product, both consumer and industrial, so long as it fits within the dimensions of a standard display peg and does not weigh more than a few pounds.

7. Eco friendly:

Since most blister packs are made of PET or PVC and aluminium, recycling them may be time-consuming and expensive due to the need to separate the elements. Some municipalities still don’t recycle blister packets, although many others do. Before discarding anything, it’s best to give it one last look.

You can’t recycle empty blister packs for medicines and tablets, so just throw them out with the rest of your trash. However, the cardboard packaging of the pills present in many medical stores is reusable or recyclable

Some businesses have developed plastic-free, eco-friendly blister packaging, but it has not yet found widespread usage in the packaging sector.

However clamshell packaging on the other hand is more recyclable and eco-friendly. It’s easy to recycle clamshells since they’re often constructed of PET plastic. Since PET plastic is biodegradable, Clamshells, especially those used in the food business, are in high demand due to the increasing amount of recyclable Polyethylene terephthalate (PET) content.

Step to Manufacture Clamshell and Blister Packaging:

As we have discussed earlier that clamshell and blister packaging resembles each other in many ways. Therefore their manufacturing procedure is also the same. Let’s have a look at the main steps:

  • Making a picture or sketch, based on the intricacy, of how the package should look is the first stage.
  • The second phase is designing the individual parts that go into the whole. Prices, quantities, designs, fabrication, packing, etc., may vary.
  • Third, you’ll need to prototype each part of the packaging and receive sample confirmation.
  • the last step is to manufacture the package after ordering the necessary materials, tools, and fixtures. Wait durations might be ranging from three weeks to six weeks or more, based on the specifics.
