What is Strip Packing Process?
The process of Strip Packing entails packaging of pharmaceutical products consisting of lozenges, tablets, capsules, etc. between two sheets of heat-sealable foil like paper-poly and aluminum-poly.
You seal the pharmaceutical product inside pockets created within two, continually moving foil sheets.
The area about the pockets creates a hermetic seal hence providing a specific shelf life to the items contained within it.
Strip packs offer an optional mechanism of the pack for a unit dosage.
You can produce strips from single or multi-ply substances.
This is practical provided you can seal the two inner plies using heat or pressure (for example cold ‘self-adhesive’ seal).
The materials used in making the strip packs vary from reasonably permeable plies to those that include a foil ply of adequate thickness and efficiency of seal.
Irrespective of the type of ply, you will be able to produce hermetic seal for each dosage.
Production of strip packs normally happen at lower speeds and equally, take up bigger volume than blisters.
Strip Forming Material
Strip packs compose of one or two plies manufactured from:
- Regenerated cellulose
- Heat Sealable Cellophane
- Heat Sealable Polyester
- Paper / Polyethylene / Foil
Basically, you form a strip pack by introducing the pharmaceutical product which stretches a pocket area in the process of insertion.
As well, the formation of the strip pack can be through a preforming operation before filling.
The second technique offers less tension or more controlled production to the pocket area and minimizes the material required by 20–35%.
It is possible to form either one or both sides of the plies mechanically.
However, you can only apply this process to substances which will ‘extend’ without tearing.
Strip designs are very elementary, as the emerging products are always square or rectangular strips.
Strip packaging of drugs
Nonetheless, the pocket part can be square, round, or oval.
The pocket area is crucial to the shape, thickness, and diameter of the pharmaceutical product.
If the pocket is excessively ‘tight,’ tearing, creasing of the seal area or perforation of the pocket circumference may take place.
The width of the seal may be as low as 4 mm; nevertheless, most strip packing machines usually employ 5 mm.
Broader seals may be necessary in case there is a possibility of wrinkling of the seal area.
Advantages of Strip Packing Technique in Pharmaceutical Industry
- Strip packaging gives a more user-friendly packaging alternative compared to bottled capsules and tablets.
- It offerscost-effective packaging option for highly sensitive pharmaceutical products.
- It is a secure and an ideal packaging technique for protection and supply of pharmaceuticals.
- Strip packs are the same size of the tablet or capsule in question. This makes the pharmaceuticals appear organized, separated, and secure.

Strip packaging machine vs. blister packaging machine
Normally made up of a feed mechanism, product insertion, and heat sealing system, and a guillotining mechanism for cutting to size.
Product feeding is commonly through a vibratory bowl having feeding tracks (normally up to a maximum of 16).
Conversely, the product feeding can be via a rotating table with a sweep or drop.
Most strip packaging machines use a vertical feed (gravity drop) though sometimes the web is driven horizontally using a platen-type sweep.
Recesses either in a platen or more often in a heat sealing cylinder, create the pocket area of the strip pack.
The machine makes a circumferential point seal between two intermeshing cylinders.
The maximum speed of the strip packing machine depends on the size of the products and gravity.
Typical machines can achieve a maximum speed of 250–300 per track with a 325 mg (five grain) kind of aspirin product.
A vacuum extractor helps in removing powder, chips, among others while a rotary die cutting or guillotine motion or scissors helps in cutting the arising web.
You can add extra stages into the machine like printing, batch coding, perforating, etc.
Contrary to blisters, perforation does not commonly add to the seal width, since pocket seal are theoretically 5 mm or more.
Majority of strip packaging machines employ two distinct webs though at times you may apply a single centrally-folded web.
It is possible to use two different plies (top and bottom) so long as the sealants are compatible.
Strip packing machine allows you to fill several different sizes of strip packs with a variety of solid dose products consisting of capsules, tablets, powders, or liquids.
This enables you to customize the pharmaceutical packaging to achieve your specific needs.
It is important to note that there is close relation between strip packaging and sachet packaging.
In some scenarios, it might be difficult to tell the difference between the two.
Modern strip packing machines allow you to generate significant amounts of strip packs very fast.
They can give strip packs in single or dual strip configurations with perforations to aid in opening the strip without damaging the product.
Blister packaging vs strip packaging
With strip packaging machine, you can semi-automatically or automatically pack a broad range of pharmaceutical products.
Additionally, it is very easy and simple to operate most strip pack machines.
You simply feed the product via the hopper and the feeding mechanism moves to the heat sealing roller cavities.

You see, a strip packing machine is quite large, and obviously, it means that that it has numerous features.
In fact, we have only mentioned a few of them here, which we consider somewhat key.
So in the next question, I want us to look at the quality standards of the strip packing machines in the market.
Quality Standards for Strip Packing Machine
Knowing the quality standards for a particular strip packing machine is essential by any measure.
You see, several manufacturers produce these types of machines.
So at times, it becomes difficult for you to know the specific one which meets the approved quality standards.
So I will describe the significant standards for this machine and highlight a few elements regarding the same.
Well, cGMP is an initialism of the current good manufacturing practice.
Essentially, cGMP refers to the practices needed to conform to all the guidelines endorsed by agencies which control accreditation and licensing of manufacture of various instruments.
These guidelines primarily outline the minimum requirements that the machine manufacturer needs to meet as an assurance of high-quality consistency.
The key purpose of the cGMP as a quality standard is to always prevent you as the end user from whichever form of harm from the machine or product.
This standard also stipulates that the product conforms to all the required quality checks.
It is usually ensured through the effective use of quality management system.
The agencies that oversee good practices in the manufacturing of this type of machine vary from one country to another.
CE Marking one refers to a certification mark that indicates conformity with safety, health, and environmental protection standards, particularly for the European Economic Area.
The two letters CE are initialism for a French word ConformitéEuropéenewhich, in other words, means European Conformity.
Basically, this standard refers to the manufacturer’s declaration that the equipment or product is compliant with all the relevant European health, safety, and environmental legislation.
One of the CE tenets as a mark of quality is that it’s only the manufacturer that can affix the mark on their product.
In other words, once you put it on your product, you basically claim to comply with the European standards.
Affixing the mark is also an indication that the manufacturers take responsibility for the conformity of the machine or product with all applicable requirements.
RoHS is another fundamental quality standard for strip packing machines you find in the market.
Apparently, it is an initialism of the Restriction of Hazardous Substances.
This standard originated from the European Union, and in some instances, it is referred to as Directive 2002/95/EC.
What it does is that it restricts the use of some specific hazardous elements that are found in electronic as well as electrical products.
For instances, some of the substances banned under the RoHS include mercury, polybrominated diphenyl ethers, and cadmium, among others.
This standard is essential because such restricted elements are often hazardous to the surrounding and pollute landfills.
It is thus applicable to any manufacturer that sells this machine as a whole or any of its components.
The RoHS ensures compliance of the standard by engaging its dedicated staff and high-end equipment as well as workstations.
This refers to an international standards organization which creates and publishes voluntary consensus technical standards for a wide range of products and systems.
ASTM is an abbreviation for American Society for Testing and Materials.
Interestingly, ASTM is an essential quality standard even for strip packing machine.
However, it doesn’t play any role in enforcing compliance with its standards.
So the standards of this body can only become mandatory if referenced by an external contract or government.
It thus means that it’s upon the corporations that do international business to choose whether or not to reference a particular ASTM standard.
It refers to the international organization for standardization.
Primarily, there are quite several ISO quality for different products.
In this case, though, we’re interested in one that’s related to strip packing machine.
ISO 12100:2010 is the quality standard that describes the safety of the machine, mainly the general principles for design.
This standard specifies the principles of risk assessment of the machine as well as the risk reduction to enable designers in achieving the objective.
What happens is that these principles based on knowledge and experience of the design, use, incidents, and other risks associated with the machinery.
· FDA Requirements
This refers to standards for protecting and promoting public health through the control and supervision of pharmaceutical drugs and other related elements.
It is an abbreviation for the Food and Drug Administration.
So it happens that this agency outlines a wide range of rules and regulations revolving around food and pharmaceutical processing and consumption.
Therefore, it has a responsibility when it comes to the approval of the machines which manufacture these particular products.
FDA analyzes, tests, and examines the strip packing machine and approves that its benefits outweigh the potential risk.
In other words, manufacturers need to make sure that inspection, measuring, and test machine is fit for the intended purpose and can provide valid results.
So these are the key quality standards for strip packing machine which you ought to know.
They are essential and make it possible for you to obtain the best results in one way or the other.
Difference between Blister and Strip Packaging
At some point, you’ve bought products, whether pharmaceutical, cosmetic or food, that come sealed in a plastic casing.
It would be important if you know the process involved in packaging such products in such types of packaging.
Blister packaging vs strip packaging
Of course, they come in two categories, which in many instances seem to be difficult to distinguish from one another.
In this section, we want to look at the major differences between blister and strip packaging.
Ideally, one of the critical difference here is that strip packaging doesn’t have a cold formed or thermoformed cavities.
This is to mean that in strip packaging, the pack is formed around the capsule or tablet when it’s dropped to the sealing area between sealing molds.
It happens that blister packaging has two major types of configurations;
- One is where the cavity is constructed of clear, thermoformed plastic. The lid here is formed of clear plastic and or better still a combination of plastic, paper, and foil.
- The second type is one which consists of foil as the significant component of both webs, where cold stretching is used to create its cavity.
Now when it comes to the production of blisters, it is essential to know that you can form them using these three methods;
- Cold forming
- Thermo-cold complex blistering
Thermoforming essentially is about wrapping a plastic sheet from the reel and then guide it through a pre-heating station on the blister line.
It goes through a dedicated process and at the end of it, is cooled to make the plastic rigid and allow it to maintain its shape after removal from the mold.
Cold-forming, on the other hand, revolves around using an aluminum-based laminate film by pressing it into a mold using a stamp.
The aluminum material will elongate and also maintain the formed shape.
The blister packaging consists of four primary components which include the following;
- The forming film
- The lidding material
- Heat seal coating
- Printing ink
Generally, we have three main types of blister packing machines, which include;
- Thermoform blistering machine
- Cold form blistering machine
- Thermo-cold complex blistering machine
Now, on the other hand, we have strip packaging.
Strip packs ordinarily present an alternative form of the pack for a unit dosage.
You can as well produce strips from single or multiple materials given that you seal the two inner plies by pressure or heat.
Production of strip often packs on low speeds and tends to occupy a greater volume than blisters.
Strip packs consist of one or two plies made from the following materials;
- Regenerated cellulose
- Foil or any combination.
Well, the good thing with strip packaging is that it provides a more user-friendly packaging solution than bottled pharmaceutical products.
It also allows you to consume a single tablet without interfering with the packaging of other tablets.
The process of strip packaging is quite straightforward but at the same time involving.
You can form it by introducing an item which extends to a pocket area during insertion.
During the process, either one or both sides of the plies are formed mechanically.
However, the process is only applicable to materials that can stretch without tearing.
Comparatively, the strip packaging machines are quite smaller than those for blister packaging.
The former consists of a feed system, product insertion with heat sealing, and a guillotining operation to size.
Most of the strip packaging machines usually use vertical feed, but occasionally the web runs horizontally with a platen type sweep.
Additional stages that you can include in the machine include, printing, batch coding, and perforating, among others.
Compared to blisters, perforation in strip packaging does not add to the seal width, and most machines tend to use two separate webs.
The designs for strip packaging are quite basic as the emerging units tend to be invariably rectangular or in other instances, square strips.
Well, from the comparison, it is apparent that strip packaging offers excellent protection and superior to blister packaging.
It is also clear that you can find certain sophisticated machines which offer high-speed strip packaging compared to blister packaging.
How to Troubleshoot Strip Packaging Machine
