Suitcase history

It is said that it was the Roman legionaries who invented the first travel suitcases to enjoy tourism thanks to the work of exploration through the Roman routes.

The suitcase, an indispensable element in the trip since ancient times. An object that must be strong and resistant on the outside, but also delicate with all the fragile objects that are transported inside. The suitcases have been growing in size, style and practicality to adapt to the growing tourism of our days.

Already in the 19th century , travel bags began to take the shape they more or less have now: a robust and durable construction to support long roads. They used to be made of wood and cowhide. Little by little, the holidays became a sign of status, so the quality of the suitcases somehow reflected belonging to a certain social class.

In the 20th century, with the rapid development of mass transportation, the suitcase fragmented its features to adapt to different uses, using the concept of “family”. In this way suitcases of different sizes were created for the different types of trips that were to be made.

In 1970 the first trolley suitcase was born. The luggage industry Briggs & Riley patented a suitcase with four wheels and a piece of rope to be able to pull it. Perhaps this was the first of the rolling suitcases and shortly afterwards the metal trolley appeared to airports and stations, to transport the luggage inside the facilities.

Already at the beginning of the 21st century, suitcase manufacturers opted for new types of suitcases that merged the structure of the trolley with the traditional suitcase. Since then, the suitcases are constantly being renovated, trying to offer the client more comforts and better mobility. Even the big firms manufacture and design their own suitcases.

Today, it is still an indispensable object of a trip, but it is also an aesthetic and modern element. Manufacturers produce unique cases that are increasingly comfortable, practical and modern.

Manufacturing materials

Materials of the Flexible Suitcases: The most used materials for the manufacture of this type of suitcases are polyester and nylon. The material of the soft suitcases is woven. The exterior is usually 600 or 1200 denier polyester, depending on the thickness you want to give to the fabric. There are also other fabrics such as nylon, jacquard, three tone or also polyester combined with EVA. The latter is a rubber or thermo comfortable material, washable, with good resistance to climate and chemicals and low water absorption.

  • POLYESTER: It is the most used material in the manufacture of flexible or soft travel bags, it is resistant to moisture and abrasion. Its resistance and weight depend largely on the deniers it has: The more deniers, the more resistance. The most basic are 600 × 300 deniers, but from 600 × 600 to 1800 we will have much better results in terms of resistance.
  • NYLON: It has the characteristics of being very resistant to abrasion as well as being a very light material. What gives lightness to the travel suitcases made of this material. It is a very elegant textile fiber. Its quality and strength is also measured by deniers. Gives a better finished look, providing durability to the suitcase and is lighter.

Rigid Suitcase Materials Rigid suitcases are less flexible and more resistant. The materials used in their manufacture are: ABS, POLYPROPYLENE AND POLYCARBONATE.

  • ABS: It is a new type of plastic very resistant to impact, hard and with a high resistance to abrasion. Depending on its quality, it will give the suitcase more resistance and robustness, resistant to scratches and impact, hard and rigid.
  • POLYPROPYLENE: It is the material par excellence for the manufacture of suitcases, it has a high hardness and resistance to abrasion, it is the heaviest material of the three, used for 4 × 4 suitcases, since it gives security and corpulence. It is a high hardness, abrasion resistant, injection molded semi-crystalline thermoplastic. It is surely the heaviest plastic, although the latest innovations have managed to produce it much lighter.
  • POLYCARBONATE: It is a very flexible thermoplastic and resistant to impacts and extreme temperatures, the lightest of the three materials, it is the most used in high-end, exclusive and expensive suitcases.

Parts of a suitcase

  • To facilitate the location of objects, suitcases have trays or interior or exterior compartments
  • With different types of closure: zip, with the possibility of securing it with a padlock ; strap and buckle closure ; suitcase with lock.
  • internal or external pockets
  • straps or rubbers to immobilize the content.
  • handle , grip, handle or handles.
  • wheels .

Classification and characteristics

Due to their Hard or Rigid hardness, made of ABS plastic, polycarbonate, polypropylene or other rigid material, they are more resistant and are appropriate for transporting fragile objects and in flight.

  • Soft or Semi-rigid, made of materials such as nylon, leather or polyester. They are more flexible and versatile, and are suitable for introducing delicate clothing.
  • Lightweight Suitcases: Made of resistant materials, but easy to weigh, comfortable and easy to move and lower.
  • Soft Suitcases: They offer the possibility of better accommodating luggage, making the order you want in which everything is ordered easier, increasing flexibility.

For its ergonomics with wheels:

  • With 2 wheels and removable handle, very suitable for moving around airports, train stations, etc.
  • With 4 wheels and removable handle, more comfortable to maneuver, move fast, ideal for travel.
  • Without wheels, practically in disuse.

Due to their size they can be distinguished:

  • Large Suitcases: They are suitcases that have a large capacity to store objects, for trips of a week or more. They usually have a height of 65-80 cm and a capacity of around 50-120 liters.
  • Medium Suitcases: Suitcase with enough capacity to carry some things, to contain what is necessary for two or three days of travel. It is also called “cabin” or “carry-on bag”, since due to its size it can be placed in the cabin of aircraft.
  • Small Suitcases: To carry only what you need.
  • Small with handle, bag type, to contain cosmetics, generically called cosmetic bag.

There are all kinds of suitcases to travel, or for day to day. Depending on each situation or place:

  • Travel Suitcases: They are the ideal suitcases to go on a trip, the resistance of their materials and their safety elements make them perfect for transporting what you need.
  • Cabin Suitcases: They are much smaller suitcases and easy to transport.
  • Children’s Suitcases: For trips or also to go to school.
  • Aluminum Cases: They provide strength and durability, they are made to last practically a lifetime.
  • Suitcases without Zipper
  • Makeup Cases
  • Foldable Suitcases
  • Computer cases

Load distribution in the suitcase

There are various organization and folding methods to save space.

  • Travel list .
  • Put the socks or accessories in the shoes to take advantage of the space.
  • Roll up soft clothes and fold those that are stiffer.
