The features of flexible packaging and the factors to consider when selecting the right type of flexible packaging for a product.

It refers to a number of materials that are used in wrapping and sealing, as well as in providing protection to goods. People do not realize the extent to which their lives involve products that are packaged with flexible packaging solutions in mind, from snacks and cereals to pet food and even medical devices. Today, the flexible packaging market offers countless bags, pouch, and film options for various products, and the choice of appropriate type directly affects its sales and ecological friendliness. In this guide, all of the important issues concerning the flexible packaging decision will be highlighted in order to assist you in identifying the right flexible packaging forms to address your goals and objectives.

Related to your product, you need to establish the following to know your packaging requirements:
The first step is therefore to evaluate your individual product’s requirements for containment, protection and display. Important questions to answer include:Important questions to answer include:

• What is the form of the product that you want to export – solid, powder, granules or liquid? What should be the method of sealing of the package, its construction that enables it to contain certain substances, or its design that enables the substances to be dispensed?
• Is your product sensitive to external conditions such as oxygen, moisture or any other component of the ambient environment to maintain the shelf lives and quality? 
• What sorts of filling and sealing equipment do you currently possess or have intentions to acquire? In what way can that restrict choices in packaging?
• Is there a need for transparent packaging or at least easily see through so the contents can be displayed?
• Is there a necessity for your product to possess tamper evident characteristics or be resealable for the safety and benefit of the consumer?

It is best to sort out your packaging specification in detail at this stage to avoid costly changes deep into the project. Record this information for further comparison in terms of different packaging format when making your decision.

Consider Target Consumer Preferences

In addition to ensuring the technical requirements of packaging in safely containing and preserving the product itself, your choice of flexible packaging should also be appealing to your target consumer base. Aspects to consider include:

Convenience: Easy-opening attributes, sliders, resealability, and suitability for on-the-go consumers tend to be important for the mainstream consumers. Other formats that are preferred by moms include stand-up pouches due to the convenience when accessing the products.

Eco-consciousness: Eco-friendly packaging using post-consumer recycle materials or packaging material that is ready for recycle is appealing. Besides, thin transparent films that allow minimum material usage and at the same time protect the contents also find favor with the growing number of eco-conscious consumers.

Lifestyle suitability: A way that active consumers might prefer their packaging is lightweight, durable flexible, that can be thrown into a bag. Children labeling preferences lean towards bright colors, simple shapes and characters. Organic, and specifically, polyethylene and polypropylene as well as other chemical-free packaging materials have more preference among health-conscious consumers.

Personalization: The target audience is the wealthy consumer who prefers high-quality packaging with ‘added value’ from a design perspective and personalized look. Subtle hierarchical differences such as matte and gloss films, textured paper stocks, metallic foils and holographic effects are evident in luxury goods packaging.

Conduct of the application process should be guided by an understanding of the users. If possible, one should involve the target group of consumers in the selection process because they will provide a firsthand information. 

Compare Flexible Packaging Options

Now that you have determined what product needs already exist and what consumers may need in the future, you can now properly evaluate promising flexible packaging categories against the criteria you have listed as well as the costs and manufacturing effectiveness. Leading options include:

Stand-Up Pouches

Standing pouch or bag packages with a bottom increase in width are one of the most rapidly growing categories of flexible packaging. Variations include clear viewing panels for the products, flat or thermoformed pouches, and Velcro zippered strips. Advantages are its flexibility, an exotic appearance, and Consumers’ lightweight carrying around. Challenges are closely related to limitations which have been observed in sphere of high-speed filling.

A flat pouch is one where the bottom gusset is formed at a right angle to the top of the pouch while, a side gusseted pouch is one in which the bottom gusset is formed parallel to the top of the pouch. 
Though they have similar design to stand-up pouches, they do not include the bottom gusset, and as a result they are easier to fill and seal. As a variant of pouch, films are also available which offer good product visibility and the accompanied shelf presence at relatively low material cost. However, they lack stand-ability.

Stick Packs

Ideal for powdered products, single use liquids and the nutraceuticals, these slim packets are very portable to allow for straight to mouth dispensing. They require minimal shelf space but have great product presence and allow high speed filling. Some disadvantages include inability to seal again or reopen after use.

Bag-in-Box Packaging

Often called flexi-bags, this packaging involves a stiff carton surrounding an interior soft bag containing products that can change their form, such as liquids. As consumers utilize the product, the bag shrinks, offering the outer carton for branding and labeling space to keep the contents fresh. Perhaps one of the key strengths of this format is that it helps to prolong the shelf life considerably. For instance, it works to enhance sustainability efforts by reducing the use of packaging materials. Some of the tradeoffs associated with implementing this approach include the following: higher costs of production, and multi-step production to produce the same amount of goods compared to the traditional approach.

Select Appropriate Packaging Materials  

Selecting the right material for flexible packaging apart from the format and design style influences the packaging’s functionality and its aesthetic. Many feature laminations joining various films to attain the maximum moisture, gas, and light resistance besides ensuring the seal strength and anti-puncture properties. Top options include:

Polyethylene: Since low density and linear low density polyethylene have low density, the films have good transparency, stretchability and wrinkle resistance during forming and filling with lower cost. Perceived control is slightly restricted since it has moderate barrier properties.

Polypropylene: Considered to have high transparency and gloss, polypropylene films also offer good moisture barrier characteristics and increased thermal stability. The review of this type of gasket also has its demerits such as being easily affected by grease or chemical interaction as well as having high costs of the material.  

Nylons: Semi-crystalline and highly oriented nylon films with thickness ranging between 0. 1 to 1 micron exhibit high oxygen and flavor permeability. They also do not get punctured, at the expense of some costs and that some of them let water/vapor pass through them.

Ethylene vinyl alcohol (EVOH): While it is slightly more costly than EVA and not advised to be used as a single layer, EVOH copolymer films provide the finest barrier to gaseous permeation thereby enhancing the freshness preservation capability of the films when used as a sandwich layer laminates with polyethylene, polypropylene or nylon.

Determine Appropriate Sustainable Options

As there is increasing concern towards packaging waste and consciousness towards sustainable packaging, consider the environmental aspects that entail production process, type of material used, recyclability and others. Tactics such as the reduction in materiality through films thickness also work towards lowering footprint as well as cost. Some leading trends include:

• Films derive from biosources; the films are produced using feedstocks such as sugarcane.
• Another sustainable bioplastic is plant-based bioplastic sourced from corn and potato starch.
• Retail compliant films for locations with commercial composting 
• Single layer and glass like films inclusive of material with other materials with possibility of being recycled 
• Films with post-consumer recycled content that are related to the circular economy

Analyzing the compatibility of machinery for the organization and the costs.  
Another aspect that affects your flexible packaging choices is the filling, forming and sealing machines employed in your production. Solutions that are currently available for vertical packaging involve the use of VFFS systems owing to the increasing flexibility, compactness and integration of forming, filling and sealing processes. But in case horizontal wrappers, rotary fillers and other machinery styles would better correspond to your existing investments.

Be cautious with tactical and short-term thinking and ensure that TCO is taken into account. What is more, reducing the first cost by choosing cheaper materials, using lower quality equipment when upgrading to a high speed or sacrificing the product look and quality to make a better price do not make sense. Choose the flexible packaging that is ideal for your strategy and goals of your business.

In Summary

These are: understanding product technical specifications, defining target consumer requirements, comparing flexible packaging categories and materials relative to those requirements, sustainability, manufacturing compatibility, and costs offer a comprehensive selection process. Not all these factors may necessarily propel each decision made, but this broad perspective will help in ensuring all packaging is in tune with the product and business vision, as well as consumer pleasure. Joining with proficient flexible packaging manufacturers as a knowledgeable ally can also help you steer towards wise packaging choices for an effective brand appeal.
