Unmatched Optical Clarity Drives Shelf Impact and Instant Recognition
What makes clear PET plastic the gold standard for visibility
Packaging made of clear PET plastic creates almost the same visual clarity as glass, with a low refractive index of 1.57 and a low haze value of less than 1%. PET plastic packaging allows products to be easily seen in stores, which is a major plus for stores with a lot of competing products, as it makes it easier for customers to select a specific brand. Recent research published in Packaging Digest states that clear plastic packaging can increase brand recall by 68% increase compared to opaque or colored plastic packaging. PET plastic is great for packaging a variety of products, including fresh fruits and vegetables, high-end cosmetics, and other products that customers want to see because they can easily judge items. Transparency makes a big difference in converting customers to purchase.
Using clear PET plastic was an important factor in the success of the major beverage brand because it resulted in a 7% increase in impulse purchases at checkout.
Sales are positively impacted by the use of clear packaging, especially for a large beverage company that, as part of its labeling initiative, started using clear PET plastic bottles. The company saw a 7% increase in impulse purchases at checkout. Research supports the company's sales increase. Research conducted by Retail Touchpoints in the previous year revealed that 58% of shoppers make decisions within seven seconds of seeing an item on the shelf. The clear PET packaging allows shoppers to see what is inside the bottle. This is important for impulse buys and creates an emotional connection. Clear packaging also reinforces the quality of the product inside. Companies that use clear PET packaging are more successful than those that use colored packaging. The clear PET packaging was recognized 12% more than the colored packaging on the shelf and has an overall 20% higher perceived value to customers.
Consumer Trust and Freshness Perception Enabled by Clear PET Plastic Visibility
How clear PET plastic improves confidence in the integrity of products such as dairy, juices, and ready-to-eat meals.
Clean PET also eliminates the “fear of the unknown,” and provides a means for customers to verify the contents of a package. The majority of customers, approximately 60%, associate visible packaging with trust, especially in the perishable category.
Shoppers For dairy products, looking through the packaging helps them assess the texture, as well as any separation and the freshness of the juice with visible pulp. For ready-to-eat meal shoppers, they want to see the ingredients, as well as the proper portions.
Leading brands report an 18% increase in product returns when switching from opaque to clear PET for refrigerated items.
The purchase hesitation of customers looking through the packaging is significantly decreased by seeing intact seals, consistent fill levels, and undamaged contents. This helps convert passive browsing into positive purchase behavior.
Food-grade compliance (FDA 21 CFR §177.1630) ensures safety without sacrificing transparency.
Clear PET plastic meets FDA food contact compliance codified in 21 CFR §177.1630 while remaining fully transparent, which many other other materials cannot achieve. PET plastic is among the least reactive materials, which has been proven in migration tests involving heating and cooling cycles. Migration tests show that PET plastic does not permit migration of substances or chemicals into food, even when in contact with citrus juice, milk proteins, or greases. The implications are that food stays fresher and tastier longer, and manufacturers can use transparent packaging, which reduces food waste, meets food safety regulations, and avoids opaque packaging. Recent safety assessments of packaging show that manufacturers with compliance documentation have around 40% reduced legal risk, although it can vary greatly depending on individual circumstances.
Functional Performance of Clear PET Plastic: Displaying Oxygen Barrier Qualities to Enhance Shelf Life
With an oxygen transmission rate (OTR) of 12-15 cc/m²·day·atm, Clear PET Plastic retains quality of carbonated beverages and sensitive liquids for 6-12 months.
Clear PET Plastic provides quality protection for the comsumer product for 6-12 months, allowing to feel confident that the product will maintain its quality. Due to the chemical stability of Clear PET Plastic, there will be no chemical interaction with the contents and moisture will be repelled. Light, and shatterproof, making Clear PET plastic the perfect combination of protection and material efficiency without compromise.
Sustainability and Clear PET Plastic: Creating the Foundation for Effective Recycling and Circularity
Clear PET Plastic enables closed-loop recycling. According to the APR, 2023, 82% of recycled beverage bottles in the US are Clear PET Plastic. 82% of recycled beverage bottles in the US are Clear PET plastic, allowing for 2 key qualities of the material:
Effective Optical Sorting: Clear PET plastic’s colorless structure is easily distinguished by the infrared sensors of the MRFs (Material Recovery Facility) resulting in lowered contamination and a higher yield from the recycling process.
Value retention: Recycled clear PET (rPET) retains mechanical and optical properties close to virgin rPET, allowing for use in food-grade applications, including bottle-to-bottle recycling.
Brands committed to clear PET are in a better position to meet and exceed recycling rate goals. rPET supports the 50% rPET mandate in California and 2030 goals. Clear PET is the obvious choice for manufacturers that want to balance sustainable plastics with high performance.
FAQ
What is the importance of optical clarity for PET plastic?
Optical clarity in PET plastic allows for the brand to be recognized and trusted. In the case of food it is also a clear indicator of freshness.
What are the environmental benefits of using clear PET plastic?
The use of clear PET plastic fosters better recycling and recycling. PET plastic is the main clear material used for the 82% recycled beverage bottles in the U.S. Using clear PET plastic allows for closed-loop reuse and reduces the need for virgin plastics.
Why is safety a benefit of using PET plastic?
PET plastic has been approved by the FDA for food contact, so it will not chemically react with food, even if the food is heated. This compliance with safety regulations offers the possibility of better tasting products without losing clarity.
