Kraft paper is a type of paper that has had a long history. It’s made from wood pulp, which is then mixed with other ingredients to create various types of paper.

Kraft paper is one the most well-known types of packaging material in the world. It’s a type of brown or off-white colored paper that was traditionally made from recycled fibers, such as old newspapers and magazines. The word “kraft” means “strength” in German and it’s been used as a synonym for strength, durability, and solidity for decades.

Part 6: Side Gusset Bag Material Guide

To keep the content flavor and freshness, side gusset bag needs the capability to be the significant need. Precisely, when these packages reach to the market consumer, food flavor must be fragrant and taste the same as it is originally.

Side gusset bag is a great promotional packaging that could be used as it will encourage purchases. Stand up pouch can be printed with custom-designed artwork, up to eight colours.

Stand up pouch material structure

Ouma Side Gusset Bags are made with the Lamination of mainly three distinct layers:

LDPE(Low-density polyethylene): is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic parts for computer components, and various molded laboratory equipment. Its most common use is in plastic bags.

HDPE (High-density polyethylene): is known for its high strength-to-density ratio. This plastic is usually milky white or semi-translucent, has superior puncture, low permeability and temperature resistance, and is more rigid and stronger than LDPE / LLDPE but also tears easier and has a propensity to crinkle.

PVDC: Polyvinylidine chloride, the excellent oxygen and moisture barrier properties of PVDC make it a ideal material for packaging converters. But the high cost of PVDC tends to mean that it is mainly used in the form of copolymers.

PET: Polyethylene terephthalate, is a very strong clear glossy film, and possesses a great number of advantages, such as good moisture and gas barrier properties, tensile strength, etc.

BOPP (Biaxially-oriented polypropylene): BOPP films are easy to produce with low costs. They have good chemical compatibility and offer superior moisture vapor barrier properties.

(Kraft) paper: has high tensile strength and elasticity, good tear resistance and is designed for packaging products with high demand for strength and durability. It is used for products like single multiwall paper bags and sacks (for cement, food, chemicals, consumer goods, flour bags etc.), sale bags for bakery products, wrapping.

Aluminum foil and metalized substrates: Aluminum foil has the best dead fold properties. It provides an excellent 100% barrier to all gases, moisture and light. It is a good reflector of radiant heat, usually supported with plastic and/or paper (in multy-layer structure) because it cracks when folded. Alone does not provide an acceptable aroma or odder barrier.

Metalized PET: are polymer films coated with a thin layer of metal, usually aluminium. They offer the glossy metallic appearance of an aluminium foil at a reduced weight and cost.

EVOH (Ethylene Vinyl Alcohol): is produced by a controlled hydrolysis of ethylene vinyl acetate copolymer. It’s most important characteristic is the outstanding Oxygen and odor barrier properties. Packaging structures with EVOH provide high retention of flavors, and prevent quality loss associated with reaction of oxygen with the product.

CPP (Cast Polypropylene): offer excellent heat seal strength, good thermal stability, good puncture resistance, good clarity and fair barrier properties. The film type also has good yield economics owing to its low density. Some of the typical application areas for the film includes hot filling and retort applications, high speed application on FFS machines and bakery products.

PLA (Polylactic acid): Polylactic acid is thermoplastic aliphatic polyester synthesized from renewable biomass, typically from fermented plant starch such as from corn , cassava , sugarcane or sugar beet pulp. In 2010, PLA had the second highest consumption volume of any bioplastic of the world. PLA is compostable, but non-biodegradable according to American and European standards because it does not biodegrade outside of artificial composting conditions.

PBS (Polybutylene succinate) : Polybutylene succinate is a thermoplastic polymer resin that has properties comparable to propylene. It is used in packaging films for food and cosmetics. In the agricultural field, PBS is used as a biodegradable mulching film PBS can be degraded by Amycolatopsis sp. HT-6 and Penicillium sp. strain 14-3. In addition, Microbispora rosea, Excellospora japonica and E. viridilutea have been shown to consume samples of emulsified PBS.

Part 7: Side Gusset Bag Manufacturing Guide & Quality Assurance

Qualified side gusset bag will bring you both long shelf life span and powerful marketing. It also create a wonderful emotional connection between your brand and the consumers.

Ouma flex pack has been devoting ourselves to help achieve your success in your market. So we take the stand up pouch quality as important as our lives. We focus on each process during production as follows:

1. Order confirmation:

After having your purchase order, we will contact you and confirm each detail via email and telephone. You are welcome to reach us 7*24 by email or phone call whenever you like.

You will have our sales confirmation within 24 hours, including the size, color, add-ons and lastly the purpose. We will specify the requirement or properties you need to be included in your stand up pouch.

2. Down payment:

We will send you the proforma invoice after you sign and send back the sales confirmation. You are supposed to arrange the down payment according to the PI. Normally, it will be 30% to 50% of the order amount.

We will launch the process upon the receipt of the down payment bank slip.

3. Raw materials purchase:

Our production department will prepare all the films, and add-ons like valves, ziplock, spouts, etc.

If there is printing on the pouches, the printing cylinders will be arranged at the same time. It takes 7-10 days for the preparation of all raw materials and stand up pouch accessaries.

4. Printing:

All printing processes reproduce lines and / or dots that form an image. Printing is the process of manufacturing multiple copies of graphic images. Although most people think of printing as putting ink on paper, printing is not limited to any particular materials or inks. The embossing process uses no ink at all, and all shapes and sizes of metals, wood and plastics are common receives of printed messages.

The following major printing processes are used to reproduce graphic images. Each of these processes is suited for specific applications, such as newspaper, book, packaging bags, or textile printing.

–Relief printing:

The relief printing process includes letterpress printing, flexographic printing, and all other methods of transferring an image from a raised surface.

–Intaglio printing:

Intaglio printing is the reverse of relief printing. An intaglio image is transferred from sunken surface. It’s also known as gravure printing, photogravure printing.

–Screen printing:

Screen printing transfers an image by allowing ink to pass through openings in a stencil that has been applied to a screen mesh.

–Lithography printing:

It’s a relatively new process, dating from around 1798. Offset lithographic printing is the most widely used printing process in the commercial printing industry.

5. Composition:

The advent of composites was a revolutionary shift in packaging.Each single material has its own advantages, disadvantages and characteristics.

For example, metallic materials are brittle and not resistant to corrosion, but have excellent barrier properties; LDPE is chemically resistant, easy to heat seal, and easy to process, but its strength and oxygen barrier properties are poor.

Composite can make up for the shortcomings so that a variety of single-performance materials are combined into a new material with comprehensive performance.

The soul of composite flexible packaging lies in the composite, is the superposition of performance. This is also the technical core of the production of composite flexible packaging.

6. Curing:

After the coffee bag roll films are composited, it could not go for slicing right away. Because it takes 72 hours of curing before it’s available for next process. It’s important to make sure it’s a fully curing, otherwise the composite layers may peel off.

7. Slicing:

The roll-form raw material will be cut by slicing machines to exactly the width needed for a pouch. There will be always big quantity of film rolls, the slicing machine will cut with an accuracy of 0.1mm, and keep the roll in perfect conditions.

A perfect slicing will help to speed up the converting process. Otherwise, it will slow the production speed, and waste the raw materials, bringing lots of lots and time and costs.

8. Converting:

Most of the converting job is done by machines. After loading the stand up pouch film roll onto the converting machine, it will go through the first part of the machine, folding according to the pouch type, sealing the bottom and both edges, punching holes, adding ziplock, etc.

9. QC (Quality Control):

Product quality is the basis for the long-term development of enterprises. In order to ensure that all goods meet quality standards, we have established a perfect quality control system:

A. IQC: In-Line QC, there will be 3 production engineers keep checking each section on the production line during the whole production. In fact, the machines have auto monitoring functions, but we still arrange QC checking for 100% assurance.

B. FQC: Final QC: at the end of the production line, there is 1 QC checking each bag, and pick out the disqualified one.

C. OQC: Outgoing QC: before packing to export cartons, we arrange outgoing QC to do another 100% quality checking and pick out disqualified items in the case.

10. Packaging:

After the packaging pouches & bags are through the full QC process, they will be packed by bundles, putting into transparent poly bags. Pouches in bundles will be packed into corrugated cardboard cartons.

The packing quantity of each carton could be indicated by clients, according to different sales methods and purposes. In this way, the pouches will be packed by customized cartons specially for this order, instead of standard size. There will be extra cost for custom cartons.

There could be custom printing on cartons and labels as well. This will also cost a small amount from the client, but it will bring great help to the promotion and storage.
