When storing any gas emitting product, you need to have quad seal bags with a degassing valve. This add-on is essential for example when storing roasted coffee.Quad Seal Bag

If you are a coffee roaster and you decide to use quad seal pouches with degassing valves, you will be able to pack your coffee immediately after roasting them.

In the quest to produce quality bags with quality valves, we have two valve options we can use:

  • Wipf valve

Coffee Bag with Valve

Wipf group came up with this valve type called the Wicovalve. Although initially Wipf valves were used on coffee, today they are used on other product. Wipf is a technological development that uses a liquid (silicone oil) membrane.

When the packaged products, for example, coffee release enough gas to cause a three millibars pressure inside the pouch, the wicovalve opens to let the pressure out. After the pressure declines to around 0.5 millibars, the Wipf valve reseals.

Such opening and resealing continues until a pressure equilibrium inside the quad seal bags equals that of the outside atmosphere. The good thing about Wipf valves is they do not allow oxygen or moisture to enter your pouches. They are one-way valves.

  • Goglio valves

Quad Seal Bag

The Goglio Group are the inventors and manufacturer of Goglio valves. These are the de-gassing valves we can add quad seal bag as one of the add-ons. Golgio de-gassing valves are one-way valves.

They are made up of an elastic rubber disc, polyethylene caps, viscous layers made up of silicone oil, polyethylene plate and lastly paper fillers. A Goglio machine is used to assemble these high-performance valves which we place on 4 side bag using machines.

Such are perfect add-on valves that will never let you down. They will allow de-gassing to take place until inner- outer pressure equilibrium is attained and lastly bars off moisture and oxygen.

Note: coffee continues to releases some gas after roasting for a period of close to 7 days. With a one-way valve, your coffee quad packaging will not burst open due to excess gas.

The one-way valve will allow degassing, but no air will be allowed inside thus keeping your coffee freshness intact.

With that, your customer will be able to enjoy fresh, tasty and quality coffee.

Below is a table that illustrates the positioning distance of degassing valve from BB (bottom of the valve to the bottom of the quad seal bag).

PET (polyethylene terephthalate): This is a kind of polyester usually used for exterior limitation work. This material provides an excellent puncture and tears resistance ability to 4 sided gusset bags.

AL (Aluminum): this a metal type added to make these bags insulated from oxygen UV light.

VMPET (Vacuum metalized polyethylene terephthalate): This is a material formed after adding AL (Aluminum powder) to PET. If Al is not to be used alone, this VMPET serves as a barrier to UV light, moisture, and oxygen.

LLDPE (Linear low-density polyethylene): When making clear quad seal bags or white bags, LLDPE is used. It is one important material because of its heat sealable nature, stiffness degree, and tear/puncture resistance. LLDPE materials are used as the innermost layer.

SIOX-PET (silicon dioxide – polyethylene terephthalate): silicon dioxide is heated, evaporates and then forms a thin layer in PET thus strengthening it for a firm quad seal bag lamination.

PVDC (Polyvinylidene chloride): PVDC is used to increase the barrier ability of PET or BOPP. It helps in increasing the permeability resistant of these bags to oxygen, moisture as well as protecting the stored product aroma. PVDC provides a perfect gusset bag coating.

EVOH (Ethylene Vinyl Alcohol): EVOH is a perfect barrier to the penetration of oxygen, moisture, CO2, UV lights and as well maintain your product aroma.

Rice paper: In case you need nice looking, elegant, good textured and attractive bags, then we have rice paper material for you. This material will answer your wishes to satisfaction.

Kraft Paper: Kraft paper material is mostly used when packing coffee or tea. It is used as the outer most layers, and it gives your quad seal bag a natural look. Such implies an off from the farm notion

CPP (Cast polypropylene): CPP is a crucial material that gives these 4 sided gusset bags flexibility, proper sealing and helps prevent their deformation. CPP material made bags exhibit a high glossy look and excellent heat resistance.

OPP (Oriented polypropylene): OPP is the best material when it comes to high-temperature feature. Such does help your quad bags resist heat to some extent.

PA (Polyamide): We use Polyamide because it has an excellent oxygen barrier, and perfectly entraps the packaged product aroma.

On a typical quad seal bag structure, the PET/ MET PET/ MOPP (Matte) materials make the outer layer, VMPET or AL are used as the barrier and middle layer and lastly LLDPE as the innermost layer.

Chapter 7: Production, Artwork, and QA

These Quad seal gusset bags are made in a continuous web of material to ensure the perfection of end product result.

7.1 Production Schedule

The production process of Quad seal bags majors on customer satisfaction. For that reason, let me tell you how we carry on our business for mutual benefits. Below is the outline:

  • Demand Analysis

After emailing, calling or personally visiting out premises for order placing, you will meet our qualified customer care attendants.

For those who send emails, they get replied within 24 hours within business days.

Customer attendant’s primary job is to direct you to the sales department who will take down all your requirements and design regarding the type of bag you need.

All questions will major on bag purpose, but make sure every detail you need is taken down. They will need details on quantity, size, color, order expected date, mode of transportation and country of delivery (port or airport). After that, they will forward your order for product mockup.

  • Research and Development

At this stage, your order will get analyzed, designs get to be drawn, and every product blueprint is thought of. When everything of correctly thought of and the designing is done, your branding and artwork then follow.  After every detail you required is accounted for, production of your quad seal bags begins.

  • Production

Our production facility is well stocked with the latest machines used on side gusset bags production. Our quad sea bag product, on entails three main steps. Human being programmes them, but machines do most of the work. Below are the steps.

  • The feeding section

Here, the flexible materials are in a roll. Some feeder rollers are used to pull and push the packaging material through the machine where bag making process takes place. Dancer systems are used to maintain the constant material film movement. We have accurate machine because we are concerned about quality.

  • Sealing section

As the dancers maintain the film movement, the sealing process then begins. Sealing elements are kept under controlled temperature for perfect sealing, and in the process, gussets are as well made. The speed experienced during the sealing is dependent on the type of material used and bag design needed. After the sealing process is done, cutting the quad bags into quad seal bags then begins.

  • Cutting and bag Filling operation

Immediately after the sealing is done, the next process which is bag filing and cutting begin. The speed here as well is determined by the machine type and settings. Lastly, accessories attached to the main machine at the bottom are used to fix add-on features such as zippers, hang holes, valves, and others.

Our company takes pride in seven high speed and automatic bag making machines, latest color printers and non-solvent lamination machine. You do not have to worry about delivery;

  • Printing and labeling

Printing is one noble thing you cannot ignore your quad bags. Printing and labeling of quad seal bags help in attracting customers.

Our facility is equipped with the relevant machines for that.

Mostly, material films are printed before the sealing happens. Both printing and labeling at our facility are done by machines such as Semi-Automatic Labeling Machines, Automatic Labeling Systems, and Print and Apply machine. They make our work easier; bring about color, size, and labels or writing position uniformity.

7.2 Artwork

After production is done, artwork designing follows to make your bags attractive. Any artwork is done using drawings, 3D effects or VI designs according to a client requirement.

Here designing of the Quad gusset bags if done on a computer. Design templates are made and with top-notch perfection to ensure every size, measurement and structure are well illustrated before being sent to the production or manufacturing department.

Below is a quad seal bag designed template.

7.3 QA and Testing

After the production is done, bags are not shipped immediately. They must go through mass testing and inspection to ensure quality and customer’s requirements were met as part of our quality assurance process.

Quality assurance entails evidencing of defects throughout inspecting the production process to ensure the quality of four side gusset bags.

But note, although it is not possible to achieve a 0% defect rate, our defect percentage maybe 1-3%. Additionally, sampling during products testing is done since one by one inspection is not possible. Defects are classified into three categorize:

  • Minor defects which cannot render a bag unfit for use
  • Major defects which should get rectified and,
  • Critical defects that render bags unsafe.

Below are the techniques we use to check for quality.

Tensile Testing

Tensile testing is an inspection whose efforts are to determine materials used especially PP breaking strength. When supplying product like sugar, rice coffee pharmaceutical product or any heavy product, you need strong packaging, and that’s what quad seal bags offer.

Tensile testing ensures you get robust, durable and sustaining bags.

Heat Seal testing

This testing ensures the seals can sustain any tear for prolonged shelf life. If the cut seal sample meets the expected strength range, then your bags will be ready for use.

The Coefficient of Friction Tester

This testing process is used to test or measure bags sliding resistance. Materials used are tested to ensure Quad bags will be able to rest on the shelves without you worrying of them sliding off.

Gas Chromatography testing

This ensures that quad-sided gussets bags produced can hold the aroma well and bar off oxygen. If you need bags that can provide a barrier to oxygen, look nowhere else. Quad seal bags are the best decision on bags you can make.

All these quality assurance tips must get checked before your bags are shipped to you. Quality assurance testing is majored on ensuring quality service to our clients.

After the manufacturing, testing and all quality aspects are done, bags are stored in our factory storage facilities for a while before getting shipped. Our storage facilities are clean, up to beat and your bags will be safe.

After all the shipping logistics are done; of which everything happens within an agreed timeline, our transporting vehicles will deliver your bags at the port or airport ready for shipping.

Chapter 8: Packing, Filling, and Sealing

This is the last but crucial part of your effort to package quality and perfect products. No matter how quality your quad seal bags are, their packaging, filling and sealing should be looked at by a second eye.

8.1: Packing of Quad Seal Bags

Some complicated but straightforward machines do these packaging, filling and sealing. The type of machine that you are to select will depend on the speed you need, the quantity of work, your facility space and height.

There are two main types of machines used in packaging, filling and sealing.

The Vertical Form Fill Seal (VFFS)

Horizontal form fill and seal machine (HFFS)

The main difference between the two machines lies in the name. The first one operates vertically and takes less floor space but a higher height length. The latter works horizontally, take up more floor space but a lesser height.

These machines can fill and seal about 30 -300 bags per minute, but some can go higher. The speed to experience depends on the quality of the products and the type of products filled in the very quad seal bags.

8.2: Filing of Quad Seal Bags

16-quad-seal-bag-image-1

Whether you are to use the HFFS or the VFFS, the filling amount or the discrete tea, coffee or any product are measured and dropped into the bags by fillers. A third-party manufacturer is the one that provides fillers which contain augers to measure the product amount correctly. But, you can order the two equipment’s from the same packaging equipment manufacturers. If you order these filling heads from a single manufacturer, you make your work easier since you will make a single quotation and the manufacturer will take care of integrating the machine well into a cohesive system.

8.3: Sealing of Quad Seal Bags

Quad bags sealing is the last but noble step. At this point, perfection is needed to ensure the sealing is done well. For example, before the sealing is done, the machines must get rid of oxygen to ensure product shelf longevity and freshness. One of the sealing machine VFFS is highly recommended for sealing coffee. For products which need zero oxygen entrapping, Modified Atmosphere Packaging (MAP) is used. The MAP allows unwanted carbon-dioxide to escape before sealing. Secondly, nitrogen gas is sometimes flushed on the bags before filling and sealing to ensure oxygen is wholly displaced.

17-quad-seal-bag-image-1

Regarding the sealing and filling options, we the following options.

18-quad-seal-bag-image-1

Continuous VFFS packaging machine

This machine can pack 300 bags per minute of size 50 mm by 90 mm to a maximum of 300 mm by 1000mm. It has a power supply of 6 kVA and 6 bar air pressure. This is one of the high-velocity machines around.

Intermittent motion VFFS M500 packaging machineVFFS-quad-seal-bag

For all the big sized quad bags, this is the machine we use. It can fill and seal 70 big bags per minute of size 150 mm by 100 mm minimum size and 500 mm by 600 mm maximum. It requires a power supply of 208-240 V and air requirement of 12-8 SCFM. But, there are intermittent motion VFFS machines.

The machines mentioned thus come in handy in packaging, filling and sealing of quad seal bags.
