Are Free Business Cards Really Free?

You have probably seen advertisements for "Free Business Cards" someone online. How could they possibly afford to give away free business cards without making someone, somewhere pay?

It is a good question, and one I wanted to know myself. I choose a company that offered so called "Free Business Cards" and began to browse their website.

I first noticed that they didn't just have the free business cards offer, but they also sold upgrades to the free package. Is that how they make their money? Only off of the upgrades?

This particular company also sold magnetic business cards, plastic business cards, metal business cards, and other types of business cards. In addition to the business cards, they also sold company letterhead, custom printed envelopes, and other types of office stationery.

The free business cards offer was beginning to make a little more sense.

I would guess that the percentage of people taking the free business cards are mainly business people. Those people probably also need envelopes, letterhead and other office stationery. Maybe they make their money on the upsell.

But are they really free?

I decided that I should go ahead and order some of these free business cards. This way I would know for sure whether or not the business cards are really free.

I decided which company I would order from then went to the order section

The first thing I had to do was design my business card. After my design I got to the order section, are they really free after all the work I did?

When I got to the final checkout, there were many options, more upgrades available. I chose not to get additional cards. Then I had to choose not to have my free business cards laminated.

After all of this, I found out that "Free Business Cards" are really free!

An Introduction to Shrink Wrap Machinery

The shrink wrap process involves two stages – the enveloping of the pack in shrink wrap either totally or partially and – the application of heat to the shrink wrap film which activates the material’s memory of its non-stretched molecular chains.

The application of shrink wrap can be divided into two principal types – transit and display.

Transit

The purpose of transit packaging is to offer the lowest cost option for packaging. The material used is almost exclusively polyethylene, which will provide the appropriate strength at the lowest available cost. A typical application is the collation of individual packs with or without tray support. The most frequent use of the forgoing involves the packaging of a quantity of cans or bottles or cartons for distribution.

The equipment used involves a sleeve or bundle sealer working in conjunction with a shrink tunnel. Two rolls of material produce a sleeve of film around the pack, which is then processed through the tunnel. Generally, these open sleeves do not cause any disadvantages to the pack integrity although a modification can be made to the tunnel whereby an attempt is made to have the hole closed through excess, annealed film.

A considerable amount of automation is offered for this process so that one may find a full range of manual, semi and fully automatic sealers and at maximum through-put, one can find lines with speeds of up to 200 packs per minute.

The processing of polyethylene is distinguished by the need for the shrink wrap film to reach an almost melt state, after which cooling will provide significant additional shrink. As a consequence, tunnels require specific cooling devices if elevated output speeds are needed.

All of this equipment may be used to wrap individual packs where collation is not required but a degree of protection is needed. Applications may vary from radiators through to office doors and bolts of cloth.

Display

The identical processes are also applied but with display shrink film where products have a natural requirement to use a sleeve. Gift wrap and wallpaper rolls fall into this category. The principles remain the same although both the sealer and tunnel will be modified to accommodate individual rolls with appropriately small diameters.

Turning to mainstream display applications, the main characteristic is the use of a total wrap.

In every single case, the sealer must now create a flat, two-dimensional bag around the product.

The product and this bag are then processed through a shrink tunnel to achieve the desired effect.

At the most basic level, this is achieved using an L-Sealer and folded film. The product is manually placed between the two layers of film and again manually placed into the sealer. The seal is completed and the pack placed on the tunnel conveyor. This is a continuous process that also produces an element of scrap film.

Automation is applied to the seal head and also to the pack support. Then, the seal process and the removal of the pack to the tunnel become automated. Generally, this is regarded as semi-automation. The clamping of the sealer head will be carried out using either a solenoid or a pneumatic ram.

Full automation of an L-sealer will allow packs to be automatically fed into the film and through to the sealer.

Manual vs. Automatic

Over the last few years, there has been a general polarisation of the above machines into manual and fully automatic, with relatively few machines being used in semi-automatic form. A manual machine will produce in the order of 10 packs per minute whilst a fully automatic will produce in the order of 20 packs per minute and there is relatively little speed advantage to be gained from a semi-automatic sealer.

Costs also have a significant influence here since entry level equipment can be purchased at significantly less than 2000 pounds whilst fully automatic shrink wrap machinery can be purchased at significantly less than 20,000 pounds.

The conventional use of a manual sealer and tunnel has been significantly reduced by the use of combined seal and shrink machines, commonly referred to as chamber equipment. These machines have a particularly small foot print and operate generally from single phase. The sealer head incorporates a plastic enclosure whilst heat is stored within the unit so that a combined seal and shrink can take place.

The maximum output that can be achieved from a fully automatic sealer will be in the order of 25-35 packs per minute.

As a consequence, both side seal and flow wrap machines are used to offer speeds approaching 100 packs per minute. The methodology remains the same as ever – to wrap the pack in a two dimensional bag of shrink wrap film.

Frequently, flat film is used although folded film is still applied by a number of machines. The sealer will be able to process individual packs at a much higher rate through the ability to seal at an appropriately higher rate.

Cross seals involve the seal device travelling with the pack whilst side seal or overlap seal mechanisms allow for film to be sealed continuously.

These same machines may be applied to other bagging requirements – in particular the mailing of magazines.

Machinery can be specifically customised to take advantage of any shrink wrap film’s particular attributes to allow an appropriate pack to be achieved. One example of the foregoing is the modification of this process to allow for modified atmosphere packaging of food using barrier shrink film.

A Surprising Variety of Custom Containers

Custom containers include not only containers of non-standard dimensions but also containers rebuilt into houses, shops, garbage bins, and so on. By containers, we mean those large 20'x8'x8' and larger boxes used to transport everything from heavy machinery to thousands cartons of trinkets (in each box).

These containers are used extensively in international trade as they can be packed and custom sealed at the factory and then transported by truck, railcar and ship (or aircraft) to distant locations without being opened till they reach their destinations. The standardized dimensions and specialized handling equipment make it easy to transfer the containers from trucks to railcars to ships and in the reverse direction. With containers, the efficiency of transport logistics improves dramatically.

While transporting containers filled with merchandise is an economic proposition, transporting empty containers is not. Containers that come in are re-used to ship merchandise out from their original destinations. Where this is not possible because of unbalanced trade, empty containers tend to accumulate at high import destinations.

These empty containers cause problems, and hence the urgency to convert them into other uses. Let us look at some of these rebuilt custom containers.

Container Houses

A 20 feet long, 8 feet wide and 8 feet high container can accommodate a 9'x6' living room, an adequate bed that folds into the wall when not needed, several chairs that also can be folded into the wall, a counter, small kitchen unit and toilet. It would be cramped of course, but can provide living quarters at worksites. A 45'x8'x9.5' container is another standard size. It can accommodate more spacious rooms and facilities.

The containers can be fitted up inside to protect from outside heat and create pleasing interiors, and doors and windows can be cut to suit the overall design. With solar power, it can even move around with continuous power supply.

Instead of living quarters, the design can be adapted for creating mobile shops, eating-places, or other kinds of accommodation. More than one level can be built by stacking containers over one another, or by going for smaller levels.

Flat Racks

The container walls and roof can be stripped out (and recycled) leaving the four corner reinforcements intact on the floor plate. With a little modification, these can then be converted into flat racks suitable for different uses. For example, fit them with wheels and they can be moved along tracks. Cargo can be fitted inside easily, and lifting and loading are also made easier.

Several numbers of these racks can be stacked while transporting empty, saving space and cost.

Garbage Containers

Another custom container is the garbage container. The empty containers lying around wasting space can be converted into excellent garbage containers that can be transported in container trucks, and handled with standard container handling equipment. Garbage can be packed tightly inside, and removed by opening one end that constitutes the door.

Open Top Containers

Loading certain kinds of cargo, such as heavy machinery, is easier into open top containers. With the top open, such items can be lifted by crane and placed into the container. This is much easier than trying to load them the conventional way.

Custom Containers

The above examples will give an idea of the versatile applications possible with standard containers. Then there are tank containers for liquid cargo, refrigerated containers, ventilated containers for organic produce, smaller containers for air cargo and so on to fit numerous custom container requirements.

Freight Containers Transformed Logistics

Freight containers are standardized shipping containers. Shipping containers have standard dimensions, typically 20'x8'x8.5' or 40'x8'x8.5' or 45'x8'x9.5'. They have to be constructed to certain minimum standards of sturdiness to withstand the rigors of long ocean voyages and transfer from one mode of transport to another. Shipping containers meeting the standards can get CSC - Convention for Safe Containers - certification, a must for use in international shipping. Specialized trucks, railcars and handling equipment have been designed to accommodate these standard sized containers. The containers fit neatly into these vehicles (as well ships' cargo holds) and the handling equipment can easily transfer the containers from trucks to railcars to ships and in the reverse direction. The freight containers themselves might have forklift pockets (typically available only for 20' or shorter containers) that facilitate forklift handling. Standardized freight containers enhanced the speed and efficiency of cargo movement, and expanded world trade. The easy and quick transshipment of the containers from one mode of transport to another - inter-modal transport - is the main factor that makes the efficiency possible. The multi-modal transport facility also enables carrying goods across terrains like water, rail track, road and air to get from origin to destination without any disruption. Freight Container Ships Freight containers are typically shipped in "cellular" container ships, so called because the ships' cargo area is segmented into standard cells to accommodate containers, resembling a honeycomb. The cargo capacity of ships is expressed in TEUs, or twenty-foot equivalent units. The space occupied by a 20-foot standard freight container is one TEU, and that occupied by a 40-foot container is 2 TEUs. Container ships these days can carry nearly 5000 TEUs. Freight Containers and Security Freight containers are designed in a vandal proof manner. They also typically incorporate sturdy locking in the form of one double door that is secured by four locking bars extending to the whole height of the container. The locking bars have additional lockable handles that can be secured by padlocks and sealed. Packing and locking the whole container at the shipper's premises and thereafter opening it only at the consignee's premises can further increase security. Any required customs inspection and certification are done at the shipper's and consignee's premises. Considering the security, container-based shipments incur less expense for insurance against theft, pilferage and damage. Packing Freight Containers Cartons can come in different odd sizes, and the internal dimensions of containers are less than the outer dimensions. Hence dividing the outer volume of the containers into the carton volumes will not give a correct idea of the number of cartons the container can carry. For example, dividing the outer volume of a 20'x8'x8.5' container (1360 cubic feet) into the volume of a 1.5'x1'x1' carton (1.5 cubit feet) might give the misleading idea that we can pack 906 cartons into the container. The standard internal dimensions of a 20-foot container is about 19.35'x7.71'x7.83' giving an internal volume of 1168 cubic feet. Dividing this volume into the carton volume of 1.5 cubic feet gives the number 778. Even this figure is wrong because the size of the carton is an odd one. If you stack the cartons lengthwise across the container length of 19.35', you can accommodate a maximum of 12 rows. A maximum of 7 rows of such 12-row cartons can be accommodated along with width of the container, giving 84 cartons per layer. 7 such layers can be stacked along the height of the container accommodating a grand total of only 588 cartons. That leaves a lot wasted space. So you change the arrangement. Cartons are arranged lengthwise across the width of the container. That accommodates 5 cartons across the width. 19 such 5-rows can be accommodated across the container length, accommodating 95 cartons per layer. The number of layers remains the same at 7 and so the total number of cartons that can be packed this way is 665, significantly more than the last arrangement. Even now, there is wasted space that cannot be avoided considering the misfit between carton volume and container volume. Packing freight containers to full capacity thus needs some advance planning.
