2,What types of bags?

  Answer: Bottom-gusseted bag, with or without zipper 3sides sealed bag, with or without punch hole center-seal bag, with or without tear nick stand-up pouch with or without zip Quad-sealed bag, with or without air valve and so on.

3,What is laminated material?

  Answer:A material which is composed of multiple layers of different material which are joined together to form a single sheet. The component layer are bonded suing adhesives. The objective of combining different material together is to create a new material with a combination of properties not available from any single material.

4,What is “metallised” film?

  Answer:Metallised film is a plastic which has a thin coat of metal applied to it. Generally aluminum is used. The most common way of producing metallised film is known as vacuum metallisation. 

  Metallsation is achieved by heating aluminum wire until it literally evaporates and coats the plastic film. Plastic films commonly used are OPP,CPP and PET.

  The aluminum-coated film has shiny decorative surface effect. Additionally metallised film has added barrier properties and in a laminate structure can signficantly enhance both gas and moisture protection. Metallised film is often seen in applications such snack pouches coffee packs and candy wrappers.

 Answer:

 Advantages of PET

 -Greater strength resulting in better control for repeat length and slitting size.

 -Higher heat resistance (~250°C)making it the preferred choice for fast speed packing machines (OPP can only withstand up to 180°C)

 Disadvantages of PET

 -Higher cost in comparison to OPP

6,Why is Nylon needed to my bag?

 Answer:Though its price is high, Nylon film is good for oxygen barrier and impact strength.Especially when the bag is to be hot-filled through or drop resistant is needed, it is necessary.
