Why Is It Important to Protect Your Products from UV Light?

Choosing the right material for packaging products requires research. Overlooking this step can end up ruining the quality of your goods. There are several factors that should be considered before finalizing packaging—and UV exposure is one of them.

Not all materials are resistant to the sun’s rays. Sun exposure can change the molecular composition of many substances, causing physical and chemical changes. That’s why you’ll see light protection labels on many pharmaceutical goods.

Effects of UV Light Exposure

The sun produces a wide spectrum of rays, out of which 95% are absorbed by the ozone layer. But ever since the depletion of the ozone layer, not all of these harmful rays are filtered out. The high-energy UVA and UVB rays aren’t only harmful to humans, but are also highly reactive with several chemical compounds. They can break their bonds and thus change their composition.
This damage is called UV degradation and mostly affects polythene and other synthetic polymers, which include PVC, rubber and neoprene. This can result in dull color, disintegration and cracks in your packaging.
This can also cause photodegradation, which only targets the appearance and color of the packaging. It can change the color of packets or cause a chalky surface on polymers used in textile or artwork.

What to Consider Before Choosing Packaging

From the selection of materials to the degree of sun exposure, there are certain things that should be considered before you choose a packaging solution for your product. Materials like acrylics and different types of glass are stable against UV radiations. Using these materials will minimize damage and preserve the quality of your product.
Here are some things to keep in mind when looking for a suitable packaging option.

Food Packaging

Consumable goods such as beverages and even water can be affected by UV rays. Their color, odor and taste can be altered by the process of photo-oxidation. For such sensitive products, it’s better to use colored glass packaging instead of transparent plastic bottles.

Pharmaceuticals

Manufacturing pharmaceutical goods require precise chemical composition. Even a slight change can completely change the purpose of the medicine, leading to health risks. Sunlight poses a threat to photoreactive medication. Such drugs are also sensitive to artificial UV rays and must be stored in colored bottles in a cool and dark place.

The beverage company has recently trialed recycled marine plastic packaging waste, proving that plastic has an important role to play in a sustainable society.    As businesses around the world prepare to dump plastic in favor of sustainable packaging solutions, Coca Cola Co. is carving its own path to innovation. The beverage manufacturer has produced and released 300 bottles, made with 25% recycled PET plastic plucked and fished from waterways and beaches. The company partnered with Ioniqa Technologies, Indorama Ventures and Circular Seas for the project. Circular Seas helped with the cleanup and collection of the plastic waste, Ioniqa provided depolymerization technology for recycling, while Indorama Ventures supplied resin for manufacturing.     Bruno Van Gompel, Technical and Supply Chain Director for Coca Cola across Western Europe, said : “This is just a proof of concept of what can be achieved with enhanced recycling technology and how plastic can be integrated i

How you apply design and graphics on your products is crucial for brand recognition. Packaging is a customer’s very first interaction with your product—they see it, pick it, judge it, and finally make the call to purchase it. Therefore, business owners have to ensure that they follow the latest packaging trends. Minimalist Packaging Brightness may not be everyone’s cup of tea.

Advantages of Screen Printing Glass Bottles vs. Paper Labels

Image
In the year 2020, let’s make your brand packaging go paperless. All the emotions you want to put into your brand message can still be conveyed without using any sort of paper-based labels.  Did you know around 26% of the total waste in our landfill sites  comprises of paper? As a brand that aspires to be socially responsible, it’s your job to make sure you’re not contributing to any of that environmental damage. A more plausible alternative that we suggest is screen printing. Let’s take a look at some other benefits: Flexible design options From a branding perspective, you can use the entire bottle as a canvas and play to the max of your designing capabilities. Whether you’ve opted for a bold design or a classic template, you can use as much space as you want to put up the best visual expression. On the flip side, if you’re using a paper label, your design space is limited to the shape and size of the label or the bottle. Screen printing even allows you to put up a tiny logo
