Custom Clamshell Packaging Plastic Clamshells Containers :The Complete Guide
What is the clamshell packaging?
Blister packaging is a universal terminology used to describe thermoforming blister packaging. At present, the thermoforming blister package has been widely applied for different products. Clamshell packaging belongs to a kind of blister packaging, it has a container with two halves, the two halves can fully pack and protect the inside products, then joined together by a hinge to control the opening and closing of a blister, just like the shell. Due to the shape and function of this blister packaging are very similar to the shell, so it is called a clamshell box.
The main difference between the plastic clamshells and other blister packages is that other packaging doesn’t have a hinge, and the clamshell pack has a hinge, you can distinguish the clamshell and other blisters by this point.
Application of hinge in clamshell packaging
As mentioned above, clamshell boxes are joined the two halves together by a hinge. There are two types of hinge structure, let’s see what’s the difference between them:
dashed hinge clamshell packaging
The first type is a dashed hinge. The dashed hinge is more beautiful when clamshell sealing, and it is easy to fold. If you want your products in a clamshell package, not only it can be hung on the shelf, but also can stand on a flat surface to display the products, the clamshell with a dashed hinge would be a good choice. The dashed hinge and the cavity on the backside of the plastic clam shells form a relatively small inclination angle, not easy to fall. But the hinge is a dashed line, so only a part of the hinge is joined together, easy to disconnect, the fold time is more, the hinge is more likely to disconnect. At the same time, the material used to make the clamshell is the thicker, the greater the tension between the two halves when the clamshell closes, and the more likely the hinge is to disconnect. Therefore, this type of dashed hinge structure is more suitable for the inside lighter products and the clear clamshell packaging requiring a standing display of products.
living hinge Clamshell Packaging（U Hinge）
The second type is the living hinge, relative to the dashed hinge, with the living hinge in clamshell that will not be a disconnect, high reusable utilization rate.
But the dashed hinge and the cavity on the backside of the clamshell form a relatively big inclination angle when clamshell standing, easy to fall, so the clamshell with living hinge is basically hung on the shelf.
Of course, no matter which one type of hinge you choose, it will not affect the price of eco-friendly clamshells when producing bulk.
How to distinguish Three Kinds of Structure of Clam Shell Packaging?
The two halves of the plastic clam shell boxes are also called cavities, which can be customized according to the products’ sizes, shape, or requirements. There are three kinds of structure of the clam shell cavity tray, Single-Sided cavity’s clamshell, Double-Sided cavity’s clamshell, and Tri-Fold clamshell.
Single Side Storage Clamshell Packaging
The Single-Sided cavity is that the cavity (used to place the product) is convex on only one side of the clamshell packaging, its other side is flat, easy to hang on the shelf, save goods space. It is generally used for packing products with small thickness.
Single Side Storage Clamshell Packaging
The Double-Sided cavity is that the cavities on two sides of the clamshell are convex, so it is generally used to packaging the products with relatively thick thickness. If uses the clamshell with a Single-Sided cavity to pack the relatively thick thickness’ products, it needs to use for the thicker material, and the blister clam shell molds are also more demanding, its cost will be relatively high. But if uses the clamshell with Double-Sided cavities, the slots on each side have a certain depth, so the container can use a thinner material, and then get the lower costs. On the other hand, customers can observe the inside product from both of front and backside at the same time, which is more convenient for your consumers to know your products in advance and increase their purchase desire.
Tri-fold clamshell packaging
Tri-Fold clamshell is quite special and used for packing products that are heavy or need to stand firm. Tri-fold clamshell has a convex cavity on three sides and two living hinges, after clamshell closing, the bottom of the blister package will form a rectangular plane, and the side elevation of the whole packaging shows up a regular triangle. As we all know, triangles have the characteristics of stability, firmness, and pressure resistance, so this triangle bottom can provide the stable platform for the products of the center of gravity imbalance. Of course, it is the most difficult for producing. From plastic clamshell packaging‘s structure design and the original sample mold production, must choose experienced clamshell packaging manufactures, slight size difference and clam shell mold irregularities will lead to the final assembly of the mismatch, resulting in standing instability or tilt.
Not all clam shells are created equally. Although we strive to provide our customers a very competitive price, we will not sacrifice quality to do so. All products are tested for clarity, wall thickness, hinge strength, and “open and closeability.”
The 3 Main Advantages Of Clamshell Blister Packaging
The first advantage of clamshell blister is save the labor time to assemble the inside products. The workers just need to put the products into the cavity, then close the clamshell blister packaging. That’s all.
The second advantage of clamshell packaging is the clear material shows the inside products well and protect the inside products from moving. The clients who pay more attention to protect the inside products during transportation would choose the clamshell blister packaging to pack their products.
The last advantage of clamshell blister pack is the cost. If you want to control the cost of packaging, clamshell blister would be a good idea. It would be cheaper than box packaging.
Disadvantage Of Clamshell Blister Pack
In order to fix each item in clamshell packaging safely, we need to customize the clamshell packaging mold for you separately, which will produce a certain mold cost. However, we have a professional clamshell packaging mold department to customize various types of molds for you
Choices of three material for clamshell pack
1, PVC conforms to SGS international Standard, it can pass detect 6P heavy metals. We recommend it to use in the Philippines, India, Malaysia, and other regions.
2, A-PET conform ROHS International Standard. We recommend it to use in the United Kingdom, the United States, Canada, the Netherlands, Australia, and other countries.
3, PET-G conform ROHS international Standard, It is in higher transparency, more environmentally friendly. Toughness and low-temperature resistance, high-temperature resistance is relatively good. Its uses for more high-level products mostly. For examples Such as high-end headphones 3C digital, Snacks, or medical device field.
As you knew, where there is business, there is competition. Where there is competition, there will be good and bad points. In any material market, there will be a distinction between high, medium, and low quality. The difference in quality is not only a literal difference, but the difference in appearance transparency and cost can even be as high as 100%.
Agreen packaging will choose the latest and non-pollution and high transparency material by default. Of course for our Earth environment, at the same time, it can also provide R-PET recycled materials that meet the GRS production standards. In order to recycle A-PET materials under supervision and regulation. This kind of duplication is totally different from reusing for cost competition. It is under the consideration for the environment totally. Our recycled material is satisfying with the ROHS, SQ, FAD standards.
How to make the clamshell packaging easy to close and keep it tightly closed?
The clamshell blister packaging is different from the ordinary box packaging structure. If you don’t master the way to close the blister well, the clamshell packaging may open at any time, and the inside products will fall off and be damaged. So it is very important to keep the clamshell plastic blister closed after wrapping the product.
The clamshell blister can be closed or sealed in various ways, such as fasten the opening of the clamshell blister with a sticker. Or use adhesives, pressure-sensitive tape, staples, etc. to keep the clamshell containers closed.
But each of these methods has some shortcomings. It is not only necessary to add a closed process after packaging the product, but also to increase the time and labor cost of the packaging assembly. In addition, with these closing methods, it will be difficult for your customer to open the clamshell plastic containers once they get the product.
You can also use the heat seal method to seal the plastic clamshell packaging to prevent tampering and packaging theft. However, it is necessary to heat-seal the product with a professional heat-sealing machine after putting the product into the plastic clamshell box packaging, so this method is more suitable for customers who have heat-sealing machines.
Of course, there is the simplest way to keep the clamshell packaging perfectly closed. That is, make some buckles on the clamshell pack directly to keep it closed.
The buckle of the clamshell blister can be divided into two kinds. One is the button you can see. Usually, you can see some small grooves on both sides of the clamshell blister pack, or it will have two square buttons on the top of the clamshell, and these are the buckles of the clam packaging.
The other one is the button you “can’t see”, just like the picture below. You can see that there is a buckle like a “ladder” on the bottom of the cavity. The top of the buckle is smaller than the bottom of the buckle, so it creates an inward sloping angle. In this way, it have a frictional fit, so the buckle can make the clamshell box packaging keep closed. This structure can not only make the clamshell packaging closed tightly, but also increase the aesthetic of outlook. But this kind of buckle is a relatively high requirement for the production of blister mold, if a little unprofessional will make the buckle is not tight or it doesn’t button up.
How to make clamshell blister neatly arranged on the shelf?
I believe that many customers will have a demand, it is to save the storage space of goods. I think maybe you can consider learning something from the supermarket. Everyone knows that there are a lot of goods in the supermarket, but how does the supermarket organize and store its goods? When you go shopping, you may notice that most of the goods will be hung on the shelves. This way will not mess up the shelf but also save storage space. So how to keep the clamshell plastic blister on the shelves? I’m sure you’re smart enough to find that it adds a hanger hole on the top of the clamshell packaging, the hanger hole also knows as a butterfly hole or euro hole. The hanger hole is usually made in the middle of the top of the clamshell blister so that it can be hung up in a stable state. If your product is centrifugal, the hanger hole also can be moved towards the heavier direction of the product to get the balance of suspension. If your packaging has a large width, you can also take the structure of two hanger holes. While hanging two hooks on the shelf, to ensure the stability and safety of the product

Selection and production process of blister advertising printing paper card
The function of printed paper card
Paper cards are biodegradable and recyclable paper cards, which have the characteristics of low cost, strong vision, environmental protection, and energy-saving. Paper cards as a small part of the blister packaging. The printed paper card is displayed in the blister cavity. Customers can usually put the paper card into the double-fold blister, It can not only play a decorative role, we can also print product instructions on a paper card, or attach product function diagrams and close-up diagrams, and production company information. Through the paper card, consumers can know how to use the product and merchants can publicize the company.
Material selection of blister card
The thickness inside displaying colorful paper card of clamshell packaging We generally choose 157Grams double sides coated paper. Because it is a common material. Relatively stable quality of paper materials. The frequency of use scenes is relatively high. It makes 157grams of double-side coated paper has a good price.
Surface process of printing paper card
Single side printing or double sides printing, Colorful printing or single color, Pantone color. If you want some area or some words highlighted display, we add spot UV. If you want some words such as logo tactile, we can add an embossing effect. If clients want the product to look more high-level, gold hot stamping or silver hot stamping is a good choice.
Normally double-side coated paper is used for the paper cards of clamshell packaging. Its printing gloss is more than 95%. The front and backside of the paper card will choose glossy varnishing or lamination process to protect the graphics and text on the printing surface. But we usually suggest choosing varnishing（glossy varnishing or matt varnishing.
Because the appearance of the varnishing is close to the effect of the film, but the production cost will be lower. Paper cards with lamination normally used to better protect printed content when they are directly contacted by consumers.
Sizes of printing paper card
The size of printing paper card is making according to clamshell containers cavity. Normally its size is less than 1-2mm than clam packaging. In order to reduce error and make perfect packaging, the final size of the paper card refers to the actual size of the reserved display space for foldable blister as a reference standard.
Mould Styles For Clamshell Packaging
The mould plays a very important role in the quality of the blister clamshell packaging. Usually, there have the plaster mould, cooper mould and hardware mold for blister forming molds.
Plaster mould is easy to make, making time is also short ( about 2-4 days). It is conducive to modification of blister clamshell packaging. Compared with another molds, its cost is lowest. Due to the original color of plaster mould, the transparency of blister made by plaster mould is less than the blister transparency made by other mould. So it mainly applicable to the sample confirmation and low requirements of product packaging transparency.
Copper mould is metal molds made on the basis of plaster molds, which are relatively durable. The thickness of blister cooper mold is about 0.5-0.8mm, and the making time is about 5 days ( including the plaster mould making time). The surface of copper mould is smooth, so the appearance and transparency of the blister produced are good. Also, its mold cost is relatively low, so that it is the most commonly used blister tray insert forming mold.

Making mass product mold. After the client confirm the sample of blister clamshell packaging, engineer polish mold, the complexity of the blister determines the mould style.
Thermoforming: Thermoforming clamshell is a process of heating thermoplastic sheet and placing it over a mold until cooled. The thickness of the material determines whether the manufacturing process uses rolled sheets (thin gauge) or pre-cut stacked sheets (heavy gauge). Thin gauge material is dominant in the disposable packaging sector.
Punch processing: The large-format products formed by clamshell packaging need to go through a punching machine and divide into a single product with a knife.
Sorting and packaging: Sorting good quality clamshell which is thermoforming, without a lot of bubbles, clamshell package side is glossy,no glitches and put into cartons.
