1º.- UTILIZATION OF COATED STEELS

It is understood by coated steel, to laminated steel of low thickness, which has been protected on both sides by another metal that safeguards it from external attacks. In the packaging sector two main types are used: tinplate and TFS, and in small quantities the galvanized sheet.

TINPLATE: Tin coated steel

TFS: Chrome coated steel

GALVANIZED PLATE: Steel coated with zinc.

 

UTILIZATIONS:

MAINLY FOR: PACKAGING as

  • BOTTLES OF PRESERVES, BEVERAGES, PAINTS …
  • AEROSOL SPRAYS
  • DRUMS, BARRELS.
  • CAPSULES, PLUGS.
  • FOOD TRAYS

IN ADDITION TO:

  • PLATES AND TRAYS
  • TOYS
  • ADVERTISEMENTS AND ADVERTISING PLATES

 

2º.- FUNDAMENTAL FUNCTIONS OF A CONTAINER

  1. a) ENSURE AN EFFECTIVE BARRIER BETWEEN PRODUCT AND EXTERNAL AND DURABLE ENVIRONMENT BETWEEN THE CONTENT AND ITS AGGRESSIONS.

o      BARRIER against:

  • OXYGEN OF THE EXTERIOR AIR (extreme case: vacuum package)
  • AIR HUMIDITY
  • MICROORGANISMS
  • UV LIGHT

o      PHYSICAL AGGRESSIONS

  • SHOCK (during handling, falls)
  • STACKING (storage)
  • PRESSURE (during sterilization)
  • TEMPERATURE (during sterilization)

o      CHEMICAL AGGRESSIONS

  • CHEMICAL INTERACTION BETWEEN CONTAINER AND OUTSIDE
  • CHEMICAL INTERACTION BETWEEN THE CONTENT AND THE CONTAINER

 

  1. b) ALLOW THE MEETING AND EASY SEPARATION OF THE CONTINENT AND CONTENT
  • FILL
  • CLOSURE
  • EMPTY (separation)
  1. c) SERVE HANDLING AND STORAGE OF THE PRODUCT CONTENT
  2. d) CONSTICONSTITUTE A SUPPORT FOR THE VISUAL PRESENTATION OF THE CONTENT PRODUCT
  3. e) DISAPPEAR AFTER USE
  4. RECYCLING OF RAW MATERIALS
  5. VOLUNTARY OR NATURAL DESTRUCTION
  6. REUSE
  7. f) ALLOW AN EASY, HOMOGENEOUS AND ECONOMIC PRODUCTION OF THE PACKAGE IN ITSELF

 

3º.- MAIN MATERIALS OF THE CONTAINER

The containers mainly use the following materials for their construction:

  • COATED STEEL
  • ALUMINUM
  • GLASS
  • PLASTIC
  • PAPERBOARD
  • PAPER
  • WOOD
  • CLOTH
  • COMPOSITE
  • MATERIALS (cardboard-aluminum, paper-aluminum, paper-plastic …)
  • OTHER AUXILIARY MATERIALS. (inks, varnishes, gums, glues …)

 

4th.- CONTAINED STEEL PACKAGING: CLASSIFICATION CRITERIA

A.- FOR THE CONTENT

a.- PRESERVES: Sterilized food

b – BEVERAGES: Beer, Colas, Soft drinks, Energy drinks …

c – OTHER FOOD PRODUCTS: Oil, Milk, Syrups, Biscuits, Powdered products.

d – NO FOOD: Cleaning, Phytosanitary, Cosmetics, Pharmaceutical.

e – INDUSTRIAL: Lubricants, Paints, Varnishes, Inks, Greases.

B.- FOR THE NUMBER OF PIECES THAT COMPOSE THEM

a – 3 PIECES b – 2 PIECES c – WITH COMPARTMENTS

 

C.- BY THE WAY OF REALIZING THE BODY

a – ENGARGOLADOS

b – ELECTRICALLY SOLDIERS

c – LEAVES

 d – SAUSAGES Simple stuffing (height / diameter <0.6)

e – SAUSAGE – REIMBURSED

f – SAUSAGE -TRANSLATED – IRONING

g – ACORDONADOS

h – ENTAILED (Stackable)

i – EXPANSIONATES

D.- BY THE OPENING MODE

a – COVER OF COVER (can opener)

b – INCISIONS IN THE BODY

c – EASY PARTIAL OPENING

d – EASY TOTAL OPENING

E.- FOR YOUR CAPACITY

1/1 (4/4) 850 cm3

½, 1/3,  1/4, 1/12…

2/1, 3/2, 5/4, 5/1…

F.- FOR YOUR FORM

a – CYLINDRICAL ROUND

b – TRONCOCÓNICA ROUND

 

c – RECTANGULAR OR SQUARE:

– PRISMATICS

– TRONCOPIRAMIDAL

e – OVAL

f – OBLONGA

g – TRAPEZOIDAL

In general, cans that are not round are called ” shape

 

G.- FOR YOUR HEIGHT

A – LOW

B – STOCKINGS

C – ALTAS

They are used for a given capacity according to their height.

H.-  DIMENSIONS (in mm)

ROUND CANS: nominal diameter of lid X body height

Example: 99 x 118 (1/1 can)

SHAPED CANS: length X width of the lid X height of the body.

Example 116 x 95 x 90.5 (1/1 Jockey Club tin)
