A flexible pouch is a type of packaging made of elastic materials that are easy to be shaped after filling the product. The main material used to make flexible pouches is plastic. In this guide, you'll find everything you need to know about flexible pouches ' from characteristics, types, and uses, as well as other interesting facts you need to know.

1. Different types of flexible pouches

Different types of flexible pouches include:

• Stand up pouches: These are the most common types of flexible pouches They are called stand up pouches due to their ability to stand on their own, and they have a tear-off label that seals and reopens the package.
• Gusset bags (side gusset and bottom gusset): Gusset bags have semi-oval dents on both sides of the bag, thus making them a square or rectangular bottom. Side gusseted pouches are relatively small tan bottom gusseted pouches, so there is little product that accumulates.
• Pillow bags: Pillow bags are used to package small portions of food such as potato chips, cookies, single-serve coffee, and snack packs.
• Three-sided sealed bags: These bags are made from one side of metal foil or plastic and two pieces of metal foil heat-sealed together.
• Liquid bag packaging: Liquid bag packaging includes several different variants that are particularly suitable for liquid packaging applications. Liquid bags cost less than traditional rigid plastic liquid containers and are environmentally friendly.

5. MOQ for flexible pouches provided by Chinese manufacturers

The minimum order quantity for flexible pouches is 50,000 to 80,000 pcs, depending on the quantity of the desired product.

6. Available printing options for flexible pouches

Flexible pouches require printed information to help track products quickly and easily, such as:

• expiration date
• date of manufacture
• bar code
• lot number

Available printing options for flexible pouches include:

1) Digital printing flexible pouch

Digital printing is widely used by flexible pouch manufacturers because it can provide a clean, shiny finish for liquid pouches. Digital printing is preferred due to its accuracy, versatility, relatively low cost, and availability of packaging materials. Digital printing is a bit expensive, and it works by using inkjet printing on flexible pouches. It is a bit expensive compared to other printing methods. It offers neat and clear prints and is highly recommended. Because of its accuracy and performance, this printing option helps companies save a lot of money, labor, and time. The biggest advantage of digital printing is that it does not require printing plates.

Some of the best features of digital printing options include:

• Digital printing produces photographs and fine art printing.
• Digital printing makes desktop publishing of high-quality printed products possible.
• Digital printing enables variable data printing and advertising, allowing for a large number of printed products and personalization.
• Optimal customization and accessibility are possible with digital printing.

2) Offset flexible pouch

In offset printing, the image of the device is transferred to a blank or plate cylinder by burning the image into a flexible pouch using a laser beam. After the ink is air-dried or UV dried, the liquid bag is complete and ready to use. Offset printing is an efficient printing option because it can handle various types of materials. It also has a large capacity material that produces about 15,000 impressions per hour. In addition to being durable and versatile, offset printing is also very economical.

3) Flexographic printing

The flexographic printing option uses flexographic letterpress. This printing option can accommodate a wide range of materials. Once the digital image is ready, the laser engraving plate prints the design using methods such as a central imprint roller, inline, or stacked. The liquid bag is then finished, including cutting, folding, and stapling. Flexographic printing uses very fast-drying ink, strong adaptability, and large ink coverage.

7. Best material for flexible pouches

Different flexible pouches are made of other materials. The material largely depends on the type of product the bag is intended to hold.

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 , 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.
