Introduce

This lovely 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 coffee beans products. Kraft paper can be recycled up to seven times before becoming totally degraded. So this standup doypack can be made at relative lower cost.

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

Foil Structure

This foil materials is a reinforced structure with excellent properties for coffee beans packages. The foil structure is Kraft Paper70/VMPET12/LDPE60, with graphic as below.

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 1000 grams of coffee beans products.

Kraft Paper Standup Doypack Properties

1 Great print quality

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

Besides, 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 customers’ artwork in a vivid effect.

When the artwork is directly printed onto kraft paper, besides, 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 Barrier Performance

This kraft paper coffee packaging bag has a desgassing valve. This desgassing valve is a device that allows gas to flow in one direction. Because coffee beans produce CO2 after roasting, which puts pressure on the packaging, the breathable valve allows the gas to be released. But the one-way design can prevent the inflow of outside air.

3 High Mechanical Strength

This reinforced laminated foil is achieved with great mechanical strength, with some standard items as below.

• Tensile Strength
• Sealing Strength
• Anti-puncture Strength
• Burst Impact Strength
• Anti-pressure Property

The above tests are performed against each order, upon customer requirements, and you may check the exact values of this foil material in the Technical Date Sheet part of this post.

In our daily QC work, there is an more easy and reliable method to check if the bag strength is enough to meet the various conditions in the operations of filling, transport, loading and unloading, distribution. We perform drop test against each order, of course, the standard for this drop test should be decided against customer needs.

Here, we are going to fill 1000grams of coffee beans into this kraft paper foil pouch, and perform drops for 3 times, and check if there is any breakage for the package.

You are advised to watch the video below.

You can judge from the video, the package stays well after 3 drops, really great physical strength.
