Why does the PET film turn yellow or gray or have yellow bars? Source: Protective film factory direct sales Release time: 2019-04-29 Click: 1846 PET film, especially when it is rolled into a reel, the color turns yellow or gray Phenomenon. It can be seen with the naked eye. If there are yellow bars, you must unfold the film or observe the light. Or spread it on a white backing for better identification. Analysis of the cause The reason is the same as the gel point, yellow point and black point. Yellowing is caused by poor thermal oxygen stability of the resin or more air entering the extruder. When the resin is thermally oxidized, it produces a large amount of acetaldehyde. Because acetaldehyde reduces the antimony trioxide to antimony, the film (resin) turns gray. The appearance of yellow bars usually occurs after replacing the filter or after replacing the resin. The reason is that there may be air in the person during the replacement. , Or part of the resin stays in the machine for too long. It makes part of the resin yellow, and after the formation of these yellow resins, it is impossible to fully mix with the normal melting and plasticization, so yellow bars appear.

From humble beginnings to becoming a staple in modern-day households, laundry pod packaging technology has undergone significant transformations. What started as a convenience-focused invention has evolved into a sophisticated blend of functionality, sustainability, and user experience. Dive into the fascinating journey of the evolution of laundry pod packaging technology and explore how it has shaped the way we do laundry today.

Early Innovations in Laundry Pod Packaging

The genesis of laundry pods can be traced back to the late 20th century when manufacturers began searching for ways to combine convenience with effective cleaning power. Traditional powdered and liquid detergents, though effective, often led to issues such as overdosing and spillage. To address these concerns, the concept of pre-measured detergent doses encapsulated in water-soluble film was born.

The early iterations of laundry pods were rudimentary at best. The focus was primarily on ensuring that the water-soluble film could safely house the detergent until it came into contact with water. These early pods were basic and lacked the sophisticated multi-chamber designs we see today. Manufacturers had to overcome significant hurdles related to the stability and solubility of the film, particularly under varying humidity and temperature conditions.

Despite these challenges, the introduction of laundry pods was met with considerable enthusiasm. Consumers appreciated the convenience of a no-mess, pre-measured dose of detergent. However, the initial packaging lacked robust child-safety features, which raised concerns among consumers and led to the development of more sophisticated packaging designs in subsequent years.

Advancements in Material Science

As the popularity of laundry pods soared, the need for improved packaging technology became apparent. Material science played a pivotal role in this evolution, particularly in the development of the water-soluble PVA (polyvinyl alcohol) films used to encapsulate the detergent. These films needed to be robust enough to withstand handling and storage but dissolve quickly and completely in water during the wash cycle.

Researchers and manufacturers collaborated to create a new generation of PVA films that offered enhanced durability and solubility. These advancements ensured that the pods could maintain their integrity during handling and transportation while still providing the desired performance in the washing machine.

Additionally, the filling and sealing of these pods saw significant technological improvements. Automated processes were developed to accurately fill and seal each pod, ensuring consistent quality across batches. These advancements in material science and manufacturing processes allowed for more complex pod designs, incorporating multiple chambers for different types of detergents and additives.

Focus on Child Safety and Packaging Regulations

As laundry pods became a household essential, safety concerns regarding accidental ingestion by children came to the forefront. The brightly colored, candy-like appearance of laundry pods posed a significant risk, leading to an alarming number of cases of accidental ingestion.

In response to these concerns, stringent safety regulations and innovative packaging designs were introduced. Manufacturers began employing opaque, child-resistant packaging to reduce the visual attraction for children. Additionally, the implementation of bittering agents in the films made the pods highly unpalatable, deterring accidental ingestion.

Compliance with international safety standards became a priority. This led to the widespread adoption of new packaging features, such as child-resistant latches and safety warnings, to mitigate risks. These advancements in safety-focused packaging designs have significantly reduced the number of accidental ingestion incidents, making laundry pods safer for households with young children.

Emphasis on Sustainability and Eco-Friendly Packaging

In recent years, the tide has turned toward sustainability, influencing the evolution of laundry pod packaging technology significantly. As consumers became more eco-conscious, manufacturers were prompted to prioritize environmental considerations in their packaging designs.

One of the most notable advancements in this area is the shift towards biodegradable and compostable materials. Traditional PVA films, while soluble and effective, are not entirely eco-friendly. Innovations in green chemistry have led to the development of biodegradable films that offer the same performance without the environmental impact.

Additionally, manufacturers are exploring packaging designs that reduce plastic waste. This includes the use of recyclable materials and innovative formats such as concentrated pods that require less packaging overall. Some companies have even introduced packaging that can be reused or refilled, aligning with the zero-waste movement.

Sustainability efforts extend beyond just the pods themselves. Packaging for the pods, such as boxes and containers, are now being made from recycled materials, further reducing the environmental footprint. These efforts represent a significant step towards a more sustainable future for laundry products.
