3. Excellent Product Protection

Paper packaging provides effective protection for various products. It can be protected with extra layers or finishes to improve durability against external elements like humidity, brightness, and heat. 

4. Cost-Effective Solution

One of the most liked pros of paper packaging by businesses is the lower cost of production. Paper is relatively inexpensive in comparison to other packaging materials.

5. Consumer Perception and Brand Image

Consumers have demonstrated an increasing preference for sustainable and environmentally-friendly products. Customers perceive paper packaging as a responsible choice, which can lead to increased brand loyalty and a positive reputation in the market.

Disadvantages of Paper Packaging

While paper packaging offers numerous benefits, it also has a few disadvantages. Compared to certain alternative materials like plastic or metal, paper packaging may have limited durability and strength, making it less suitable for certain heavy or fragile items.

Let’s proceed to the next section of advantages and disadvantages of paper packaging;

1. Vulnerability to Moisture and Impact

One of the primary disadvantages of paper packaging is its vulnerability to moisture. Unlike plastic or metal, paper can absorb water, compromising its structural integrity. This makes it inappropriate for products that require high levels of protection against moisture or have a long shelf life.

2. Limited Strength and Durability

Compared to materials like plastic or metal, paper has limited strength and durability. It may not be suitable for packaging heavy or bulky items that require robust protection. Paper packaging is prone to tearing, especially when subjected to rough handling or extreme conditions.

3. Space and Storage Requirements

Paper packaging tends to occupy more space compared to other materials due to its bulkiness. This can pose a difficulty when it comes to storing and transporting, particularly for extensive operations. Appropriate storage conditions must be required to safeguard the reliability of the packaging.

4. Environmental Impact of Production

While paper packaging is environmentally friendly in terms of its recyclability, the production process itself has certain environmental implications. The manufacturing of paper requires the utilization of water, power, and substances, which can contribute to the reduction of forests, contamination of water, and release of greenhouse gasses.

5. Limited Barrier Properties

Paper packaging has inherent limitations when it comes to barrier properties. It is permeable to air, moisture, and certain chemicals. This can pose challenges for products that require a high level of protection against external elements. Additional coatings are necessary, which can increase the cost of packaging.

These advantages and disadvantages of paper packaging can help you streamline your business operations. 

Conclusion

Businesses must carefully evaluate their packaging needs and consider the environmental implications when choosing paper packaging.

By understanding the advantages and disadvantages of paper packaging, they can make informed decisions that balance functionality, cost-effectiveness, and environmental responsibility.

Polylactic Acid (PLA) is a biodegradable and renewable polymer derived from plant sources such as corn starch or sugarcane. Due to its unique properties, it has gained significant attention in various industries, including the coated paper industry.

This article explores the advantages and disadvantages of using PLA in coated paper cup applications and introduces you a more cost-effective replacement for coated paper cup raw material.

Poly(lactic acid) (PLA) replaces petroleum-based plastics like polyethylene (PE) to become a more environmentally friendly coated paper cup raw material. PLA coated paper cups have a PLA film coated on the inner surface of the cup. PLA is derived from renewable resources such as plant starch, reducing reliance on petrochemical resources and helping to decrease demand for non-renewable resources.

After disposal, PLA coated paper cups can be decomposed into non-toxic substances through proper treatment, making them environmentally friendly. The production process of PLA is non-polluting, it can biodegrade, and it cycles naturally in the environment, making it an ideal green polymer material. It aligns with global and national environmental policies on plastic reduction and bans.

Paper cup coated with traditional petroleum-based plastics required separation of the plastic from the paper prior to recycling. If not separated, the polymer could disrupt the paper’s recyclability. Consequently, many such applications were either incinerated or sent to landfills due to the lack of alternative end-of-life options.

Poly(lactic acid) (PLA) exhibits excellent safety performance. In contrast, polyethylene (PE) coated paper may oxidize into carbonyl compounds during the hot melt or coating process on cup paper, potentially emitting odors when filled with hot water. PLA coated paper, on the other hand, is odor-free and possesses antimicrobial and UV-resistant properties.

Moreover, PLA coated paper has obtained FDA food-grade certification, European DIN biodegradability certification, and American BPI certification, ensuring that its performance meets all relevant national standards.

PLA coated paper cup exhibits excellent low-temperature resistance, ensuring no leakage or deformation when used for cold liquid containers. It maintains good strength, meeting the typical requirements for coated paper cups.

However, PLA material is sensitive to temperature, with a heat resistance limit of only 70°C. Therefore, it is not suitable for storing hot liquids, as this can lead to softening and deformation of the cups.

While PLA offers adequate barrier properties for many applications, it may not provide the same barrier performance level as some synthetic polymer coatings. This limitation may influence its suitability for packaging applications requiring very high barrier properties.

For example, you can see following chart to compare barrier properties between PLA and PPC-P. It’s obvious that PPC-P offers better barrier properties than PLA.

PLA-coated paper cups are often promoted as an “environmentally friendly” alternative to PE-coated cups. At first glance, this might seem accurate, but the reality is more complex. PLA is a plant-based plastic that manufacturers claim is biodegradable and compostable. However, the key term here is “plastic.” PLA remains a plastic, with all the inherent issues associated with the material.

For PLA to be composted, it must undergo industrial composting in specialized facilities. If placed in a home compost bin, it will remain intact for many years. To successfully compost PLA coated paper cups, they need to be subjected to industrial heat of 60°C or higher. However, such facilities are limited in many regions, making it difficult to achieve the necessary conditions for biodegradation.

In simple terms, this means that PLA coated paper cups are just as problematic as regular PE-coated paper cups. Inevitably, and often without the awareness of well-meaning consumers, PLA cups contribute to the single-use plastic problem.

The raw material of plastic-free paper cups does not add any plastic coating, making them truly environmentally friendly, completely degradable, and having no negative impact on the environment. At the same time, plastic-free paper uses special waterproof technology, which can provide a certain degree of water resistance to meet general daily use needs.

However, compared to PE-coated paper and PLA-coated paper, plastic-free paper has poorer permeability resistance. If plastic-free paper cups are used or stored for a long time, leakage problems may occur. Additionally, the production technology for plastic-free coated paper is still in the development stage, with a relatively complex production process and higher production costs, making them relatively expensive and unsuitable for large-scale promotion and use at present.

Since it is unlikely that plastic-free paper cups will be used on a large scale at present, what materials should be chosen as the raw materials for coated paper cups? Here we will suggest our PPC-P products for you.

LXBIO’s PPC-P plastics offers several advantages over PLA, addressing many of the latter’s shortcomings:

PPC-P exhibits significantly better barrier properties against oxygen and moisture compared to PLA. This makes PPC-P coated cups more effective in preserving the contents and preventing leakage. It also provides excellent resistance to oils, making it suitable for a wider range of food and beverage applications.
