AGTERGROND

Die eerste verpakking se inligting is met die hand daarop aangebring en dit het baie lank geduur. Selfs die papier waarvan die verpakking gemaak is, is met die hand gemaak.

Aan die einde van die vyftiende eeu is masjiene ontwerp wat papier kon maak en ook kleurvolle ontwerpe daarop kon aanbring. Dit het die verpakking baie goedkoper en bruikbaarder vir die kommersiële mark gemaak.

Deesdae verpak groot vervaardigers hul produkte self met masjiene wat nie net die verpakking maak nie, maar ook hul inhoud weeg, vol maak en verseël.

Opdrag 20

Weet jy hoe papier gemaak word? Voorsien die volgende skets van die proses met die letter wat langs die korrekte beskrywing staan. Skryf die letters in die gegewe blokkies.

  1. ‘n Groot rol papier word verkry.
  2. Die pulp word met bleikmiddels gemeng.
  3. Die papier word verhit deur rollers sodat dit kan droog word.
  4. Die pulp word geskud sodat die vesels aan mekaar kan vassit.
  5. Rollers druk die pulp om die oorblywende water te verwyder en dit verder saam te pers.
  6. Klein stukkies hout en water word verhit sodat dit ‘n pulp vorm.

AGTERGROND

‘n Houer is die mees algemeen gebruikte vorm van verpakking. Die eerste houers is van hout gemaak, maar omdat dit so moeilik is om inligting op hout te druk, is inligting op papier gedruk en op die houthouers geplak. Deesdae word meestal houers van karton gebruik. Die inligting word dan direk op die karton aangebring.

Moderne kartondose word ontwerp in baie interessante vorms en groottes. Dit is nie net die inligting op die kartondose wat op ‘n kreatiewe wyse aangebring is nie, maar die vorm van die kartondose is self indrukwekkend.

Watter vorm van kartondoos is die algemeenste?

Deesdae verpak sekere voedselfabrieke hul ware in versierde blikke, aangesien blikke ook al versamelaarsitems geword het. Dan word die artikel nie noodwendig vir die inhoud gekoop nie, maar vir die verpakking!

Dit was na aanleiding van die maak van versierde blikke vir koekies in die 1800’s dat mense besef het dat blikke ideaal is vir die bewaring van voedsel. So het die inmaakbedryf ontstaan. Hierdie blikke word meestal voorsien van papieretikette en word na gebruik weggegooi.

what are pathogens
Don Reply
In biology, a pathogen (Greek: πάθος pathos "suffering", "passion" and -γενής -genēs "producer of") in the oldest and broadest sense, is anything that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. The term pathogen came into use in the 1880s.[1][2
