Liquid Packaging Selection: The Path to Sustainable ...

 

View Details

Today, the world is more environmentally conscious than it has ever been before. This is why choosing suitable packaging for liquid products goes beyond appeals and functionality.  Sustainability plays a vital role in shaping consumer preferences and how business is conducted. Here, we will explore factors when selecting liquid packaging, focusing on sustainability, functionality and cost.

 

 

Three Factors to Consider

  1. Sustainability: Incorporate Reduction over Recyclability

Usually, recyclability often takes center stage in sustainability discussions; research highlights that reduction holds a more significant benefit throughout the entire packaging lifecycle. Conducting a Life Cycle Assessment (LCA) is essential to evaluate your environmental impact, whether you choose rigid or flexible packaging. Understanding the complete picture allows you to make informed choices that align with your sustainability requirements.

 

 

According to a study by The Sustainable Packaging Coalition, reducing packaging waste and materials leads to a more significant environmental impact than focusing solely on recyclability. By choosing packaging solutions that minimize material usage and waste generation, businesses can contribute significantly to sustainability goals.

 

  1. Functionality that Matters: Balancing Safety and Efficiency

Functionality is at the base of adequate liquid packaging. Safe and efficient dispensing of products is vital, especially when dealing with ensuring chemical compatibility.  The Environmental Protection Agency (EPA) highlights the importance of packaging compliance with safety regulations to protect consumers and the environment from potential hazards.

 

  1. Cost: Beyond Package Material

Cost-effectiveness is a significant consideration in packaging decisions. According to a report by McKinsey & Company, packaging expenses account for a considerable portion of operating costs, with storage and transportation costs significantly impacting the overall budget. A strategic approach to packaging can optimize logistical efficiency, reduce waste, and lead to substantial cost savings in the long run.

 

 

Companies can reduce their carbon footprint and save on transportation expenses by choosing packaging that minimizes weight and volume while maximizing product protection.

Liquid Packaging Solutions – An Ultimate Guide

Liquids and beverages are notoriously tricky to package. These products require packaging that can be successfully filled, stored, transported, displayed, purchased, used, and disposed of, all while retaining the product&#;s quality. 

Liquid items are primarily packaged in bottles, pouches, and containers. These are prepared using paper, glass, plastic resins, or plastic films.

Liquid packaging with films is accompanied by liquid pouches. Plastic films are molded into various shapes for making pouches. The most widely used plastic films for liquid packaging are:

  • BOPP films
  • Aluminum
  • BOPET films

Let&#;s explore some important aspects of liquid pouches.

Types of Liquids Pouches

Liquid pouches offer a lower cost than traditional rigid plastic liquid containers and are friendly to the environment. Many types of liquid pouches are used for securing liquid goods. The essential types of liquid pouches are as follow:

1. Stand-Up Liquid Pouches

Stand-up pouches are a popular method for holding liquid contents due to their flexibility, ease of use, and ability to keep substances fresh. These pouches can accommodate products such as soups, juices, and laundry detergent.

One of the conveniences of stand-up pouches is the ability to place the label on the front or back of the pouch. Resealable labels can also be applied to stand-up pouches to preserve the good&#;s freshness by resealing the pouch after it has been opened.

Stand-up liquid pouches are made from plastic films such as BOPP, Nylon, Aluminium, and BOPET. BOPET film is mainly employed for making stand-up liquid pouches.

2. Stand-Up Liquid Pouches with Spout

This pouch is the latest innovation in the continuing evolution and development of stand-up pouches and packaging technology with the integration of closures into the flexible package.

 It features a reclosable spout that is hermetically sealed to the packaging material. This spout protects the product through its lifecycle and can be used for both liquids and powders. These flexible pouches safely contain liquid products and stand up easily on store shelves for a more effective display.

Best of all, when done correctly, spouted stand-up pouches are one of the lowest-cost options for liquid and beverage packaging. Compare spouted bags (made with BOPET film) to glass and rigid plastic &#; when it comes to quality and price, there&#;s no contest. It is mainly used for:

  • Hand Sanitizer
  • Bone Broth
  • Cold Brew Coffee
  • Cosmetic Products
  • Juice
  • Powdered Mixes
  • Dry Spices
  • Yogurt
  • Nut Butter
  • Shampoo & Conditioner

Benefits of Spout Liquid Pouches
  • High convenience: it is straightforward to access content from a liquid pouch bag with a spout on the go.
  • Evacuation: liquid pouch bags with a spout can eject 99.5% of their contents, thus reducing food waste.
  • High visibility: liquid pouch bags with a spout can be custom printed to make products stand out on retail shelves.

3. Burst Liquid Pouches

The Burst Pouch is a flexible pouch with a layer of poly-film sealed inside to create chambers. The consumer can cut the bottom of the pouch, place it into the desired container, and squeeze it, forcing the liquid to &#;burst&#; through the poly membrane and into the desired container. These pouches are usually one hundred percent clear.

The burst pouch, also known as burst bag, is the most advanced technology available for adhesive packaging solutions for two or three-component premeasured liquid systems. They are used mainly for non-edible packaging liq uids, powders, and industrial products.
