Pros and Cons of Flexible Packaging and Glass Packaging

In today's time, two types of packaging are popular for every kind of product and across the globe. One is flexible and the second is glass. Both are wonderful in their ways; however, they have some pros and cons. Before choosing between traditional materials like glass or standup bags, plastic material, you should read out the advantages and disadvantages of both the packagings.

Glass packaging

Glass packaging is one of the best choices for liquid foods and other stuff. These are the containers you use to pack ketchup, jam, juices, whiskey, pickles, and some other food items. The material has a wonderful impact on the eyes of customers. To allure the buyers, many manufacturers use luxury, vintage, and aesthetic glass to make bottles and jars. These are some of the most ancient packaging materials.

Pros of Glass Packaging

Well, this is 2020, and this is the era of trends, innovations, and uniqueness. The same is the case with glass jars and packagings. Stylish and alluring water bottles are so popular these days among millennials. They are not reluctant to spend an excessive amount of money on fancy and luxury bottles. Therefore, this is increasing your business and expanding the profit.

Another advantage of using glass as your packaging material is it retains the original taste of your food content. Yes, it can preserve the organic flavors of the drink, unlike plastic bottles.

Moreover, it can control the temperature and protects the fresh juices from heat. While plastic bottles catch the hotness of the air quickly and ruin the true flavors of the drinks. Therefore, every type of liquid food is safe in glass packagings.

Glass packaging is the best choice for carbonated beverages. Drinks can sustain much longer in these jars as compared to the plastic bottles. Therefore, if you want to store the carbonated drinks for a longer time, you should choose glass over plastic.

Furthermore, when it comes to eco-friendly nature, glass is the winner over plastic. This material is recyclable. Therefore, customers are switching their buying choices from plastic to glass.

Cons of Glass Packaging

Multiple scientific studies have shown a bitter truth about the biodegradability of glass, that it is more harmful than plastic. When it comes to the decomposing, plastic substance is less injurious than glass.

Moreover, recycling of the glass material is not so easy. The process involved in it is a little more harmful due to the high carbon footprints.

Moreover, shippers need extra care while shipping the glass packagings. Due to their weight, companies have to pay the extra shipping cost. Thus, it is expensive than plastic.

Flexible Packaging

The packaging made of foils, films, shrinks sheets, paper sheets, skin films, etc. are flexible bags. For example, plastic pouches, sachets, bags, wraps and envelops.

Pros of Flexible Packaging

Flexible packagings have various designs, shapes, and sizes. They can stand and sit with ease for every type of product.

Moreover, flexible packaging can preserve food for a very long time. The solid eatables are safe in shrink films and foils. They protect the freshness and colors of food items in the containers.

According to some recent scientific studies, plastic releases less carbon than glass. No doubt, recent awareness has lower down the sales of flexible material due to the uproar of eco-friendly substances. However, it is safe to use plastic packagings in many ways.

They are less expensive than glass containers. The first reason is the material and the second is its weight. It is less heavy; thus, it has easy shipping principles and prices.

Cons of Flexible Packaging

Flexible packagings are not recyclable, unlike glass containers. However, they leave fewer carbon footprints.

Some Necessary Elements for Modified Atmosphere Packaging

Modified atmosphere packaging or MAP has some distinctive dynamic that you cannot find in any other packaging supplies. They have some specialized machinery, gasses, and metering tools in the making process.

Therefore, today’s article is worth reading, especially for those who have no idea of modified atmosphere packaging. Stick with the blog and learn each and everything about the elements and process.

Through this write-up, you will learn what you need to produce modified atmosphere packaging. You will able to make MAP on your own.

The necessary elements for modified atmosphere packaging are gas, machinery, and testing tools.

How to Source Appropriate Gas for Producing Modified Atmosphere Packaging?

When it comes to producing modified atmosphere packaging, you need to source many elements. The first thing you will require is gas.

Apart from sourcing the gas, you should know the appropriate needs. Moreover, many of the elements are not available in packaging supply companies. You will have to buy some components online. This could the case with adequate gasses.

The one best option to find out the appropriate gas for your food products is to perform an accelerated aging test in any food science lab. This will tell you about the shelf life of your product. Moreover, you will be able to identify suitable gasses for the packaging of your eatables.

Apart from the testing through a food lab, you can hire a gas company that can identify and produce the right gas for your food items and packaging.

To know the right gasses for your food items is a paramount element. For example, meat needs more oxygen in the packaging to prevent discoloring. However, bread requires less oxygen due to the fungus attack. Both cases are different and sensitive. Therefore, find out the appropriate gas for your eatables.

Selecting the Gas Supplier

After finding out suitable gas or gasses for your food products and packaging, now you need a supplier.

Well, you can source the gas suppliers from a packaging company or a gas supply market. But, sometimes you cannot choose the best one. Thus, need to discuss your requirements and terms and conditions with at least three to four supplier companies. Moreover, you can find some solutions online. Do not hire packaging vendors for the supplying of gasses because they work with the gas dealers.

Before selecting the final vendor, you should do your research on the companies, visit the dealer, and the analysis of the packaging line.

Oxygen Analyzer

If you want to produce modified atmosphere gas, you should have your oxygen analyzer, chamber sealer, and shrink films. These are some necessary machinery and tools for making the MAP.

You cannot inject oxygen in the packages on your estimations. You need a proper handheld device to test the accurate amount. Therefore, you should have an oxygen analyzer through which you can examine the right quantity of gas in the food packaging.

Many food packages need zero oxygen and some of the meals require a small amount of gas. Therefore, the oxygen analyzer is must-have equipment should buy to test the gasses.

Oxygen analyzer has a syringe, designed in a two-way radio shape. The needle helps to inject and examine the appropriate quantity of gas. If you will have your device, then regular testing of your food packagings is easy.

Chamber Sealer

In the production of modified atmosphere packaging, the most demanded gas is nitrogen. It is the replacement of oxygen for many food packages. Oxygen has a high rate of spoiling the food in packing.

Therefore, you need a tool to replace the oxygen, called chamber sealer. The device has a vacuum technology that sucks all the oxygen from the packaging and injects nitrogen instead.

Shrink Films

In the MAP applications, you will need to shrink films to reduce the negativity of moisture and oxygen. The common sheets are polyethylene (LDPE), polyvinyl-chloride (PVC), and polyolefin (POF).
