Beneath the layers Of a BOPP bag
Woven Bags are one of the trendsetters in modern times which put the packaging industry on a new pedestal, especially when it comes to the woven packaging.
It’s needless to mention that the world of woven packaging has its own blessing in the form of BOPP Woven Bags having layers of trust, authenticity and secureness.
Since BOPP Woven Bags come with various layers, they offer a wide variety of benefits. These bags are also known as the Multilayer Bags. The most crucial layer
in the bag is the PP woven fabric. Printing of BOPP film is done using engraved cylinders through the reverse rotogravures printing technology. Next, we laminate
the film on the fabric to create different kinds of layers. Available in a wide range with exceptional qualities, we offer different types of layers in our BOPP
Woven Bags ranging from single-layer bags to five-layer bags.
Importance of layers
Different kinds of layers in BOPP bags add to their different qualities. A specific combination of the layer present in the bags protects the products from
leaking while keeping the humidity intact. In contrast, the other types of layers offer greater strength or appealing looks along with proper ventilation.
All this depends upon various factors like the number of layers, type of fabric, and so on. These different layers provide add on advantage. More layers
increases the bag’s thickness and stiffness.
Manufacturing Process
The addition of layers completely depends on the desired requirement. For making one layer bag, we use only fabric while on the other hand, for two layered bag,
an un-coated fabric roll is coated in the extrusion lamination unit. The end product which comes out of this process is called two-layered fabric roll. In three
layer bags, we use un-coated fabric roll and laminate it with printed BOPP film with the help of extrusion lamination, which acts a bonding agent between BOPP
film and fabric. In four-layer bags, one more layer is added which could either be on the innermost side of the bag (extrusion lamination) or beneath the BOPP
film (Adhesive lamination). The five layer bags have plain BOPP on the innermost side, extrusion lamination, fabric, extrusion lamination and printed BOPP on
the outermost side. The points below will help you unravel the mystery of layers:
- 1 – Layer bag – Un-coated fabric
- 2 – Layer bag – Un-coated fabric + extrusion lamination
- 3 – Layer bag – Un-coated fabric + extrusion lamination + printed BOPP
- 4 – Layer bag –
Un-coated fabric + extrusion lamination + adhesive lamination + printed BOPP (metalize or white poly film)
Inside Extrusion lamination + Un-coated fabric + extrusion lamination + printed BOPP (Note – only for flat fabric)
- 5 – Layer bag – Plain BOPP + inside extrusion lamination + un-coated fabric + extrusion lamination + printed BOPP (Note – only for flat fabric)
Material Combination
Every material has its uniqueness but when a combination of unique materials makes the final product extraordinary, then it’s a good idea to make the match. This is the reason we have chosen to add some more elements to the uniqueness, our bags offer. The materials and process we use in our different layered bags are:
- BOPP Film
- Metalized BOPP Film
- Woven Fabric
- Extrusion Lamination
