Description

You can understanding by watching the video below this 150 grams kraft papper standing pouch for chinese dates.

Introduce

This wonderful standup doypack is made of recyclable kraft paper film materials. Kraft paper is a natural, biodegradable, and compostable material which is intended for more sustainable packaging solutions for the chinese dates products. Kraft paper can be recycled up to seven times before becoming totally degraded. Therefore this standup doypacks are relatively cheap to make.

Here we are going give a further explaination on this amazing eco-friendly kraft paper package, and hope it helps you to decide your perfect packaging.

Foil Materials

This foil materials is a reinforced structure with excellent properties for chinese dates packages. The foil structure is MatteBOPP18/KraftPaper67/VMPET12/LDPE, with graphic as below.

Matte BOPP18, is short for matte finish biaxially orientated polypropylene film with most common thickness 18 microns (equals to 0.72 gauge). Compared to glossy BOPP film, it is able to achieve the final package with a fine matte visual appearance for the package at a lower cost.

Brown kraft paper in nature color with weight 70gsm working as the outside layer, good stiffness and supportive layer. Custom artwork can also be printed on outside.

VMPET12, means vacuum metallized polyester film with thickness 12 microns (equals to 0.48 gauge), is the most common used aluminum metallized films in flexible packaging field. It is with high barrier performance against mositure vapor and oxygen. The barrier performance will enable your coffee products well protected from the roaster warehouse to the consumer’s hand in a fine way.

LDPE film, means low density polyethylene film, which is the most used inner sealing layer for the coffee bag. It is able to provide enough sealing strength and airtight property for the final packages.

The final thickness for this foil laminate should be 150 microns, with tolerance +-5%. and the toughness of this foil will be enough to finalize good package profile for 150 grams of chinese dates products.

Kraft Paper Standup Doypack Properties

1 Great print qiality

The artwork is achieved in gravure printing which can print up to maximum 10 colors. With advanced print art and print defects inspection system, we are now outputting fantastic print effect against the customers’ artwork.

Actually, this amazing artwork is reversely printed on the inner side of Matte BOPP film and then laminated to kraft paper, which can keep the original colors of the customer artwork in vivid effect.

When the artwork is directly printed onto kraft paper, actually, some of the subtle and complicated effect may not be presented as the effect of printing onto substrate film, like BOPP film, BOPA film, and polyester PET film. As the porous tiny holes on the fiber plant will of course absorb much of the inks, and will cause the loss of gloss and vivid effect in human eyesight.

2 Great Standing Profile

In this doypack, we choose kraft paper with yield 70 gsm, which is a stiff and tough materials for most packages. The final packages achieved with this foil laminate MatteBOPP18/KraftPaper67/LDPE are usually with great standup straight effect. So, when the products are filled into this standup doypack, the package will be able to present good branding and sale purpose on the goods shelf.

3 Amazing Airtight Property for Zipperlock

This single track plastic zipper is applied onto the kraft paper doypack, with back and front part well melted to the inner layer of the doypack.  It enables the package to be repeatedly opened and closed with great airtight property.

Here, we are going to open and close the zipperlock for several times, and check if the air is easy to penetrate into or out of the package. Usually, we will apply a certain pressure on this closed zipper doypack, and check if the inflated doypack is easy to burst.

You are advised to have a further understanding on this test progress through the video below.
