Recently, the EU has released the draft of the Packaging and Packaging Waste Regulation (PPWR), aiming to unify the management of packaging and packaging waste, especially in terms of plastic recycling. This article will deeply explore whether paper packaging can replace plastic packaging and analyze the future trends of sustainable packaging.

Prevent the Generation of Packaging Waste
This regulation aims to reduce the quantity of packaging waste, limit unnecessary packaging, and promote reusable and refillable packaging solutions.

Promote High - Quality Recycling
By 2030, all packaging on the EU market should be recyclable in an economically viable way.

Increase the Use of Recycled Plastics in Packaging
This goal aims to reduce the demand for primary natural resources and create a favorable market environment for recycled materials.

The third goal of PPWR, that is, promoting the use of recycled plastics, has caused widespread controversy in the industry. Some voices believe that the EU should promote the use of more easily recyclable packaging materials, such as paper packaging, to replace plastic packaging.

Advantages of Paper Packaging

(1) The recycling rate of paper packaging in the EU is close to 90%, which is the highest among all packaging materials.
(2) Paper packaging, like plastic, has the advantage of low density, which can reduce transportation costs.

Limitations of Paper Packaging

(1) Poor barrier property: Paper packaging has poor barrier property, which is not conducive to the protection of perishable foods and sensitive products.
(2) Poor mechanical properties: Paper packaging is far weaker than plastic in terms of tear resistance, compression resistance, impact resistance, and wet strength.

Current Problems of Plastic Packaging
Plastic packaging is difficult to degrade in nature and is likely to accumulate in the natural environment.

Room for Improvement in the Recycling Rate of Plastics
Although the recycling rate of plastics is relatively low, there is still significant room for improvement.

Selecting Suitable Packaging Materials
Packaging materials should be selected according to the characteristics of different materials and their applicability in specific fields.

Improving the Recycling Efficiency of Plastics
In the case where more suitable alternatives to plastic packaging cannot be found, improving the recycling rate of plastic packaging is a reasonable approach.

Although paper packaging has advantages in some aspects, due to its limitations in barrier property and mechanical properties, paper packaging cannot completely replace plastic packaging at present. In the future direction of sustainable packaging, comprehensively considering the characteristics of different materials and improving the recycling efficiency of plastics are the current environmentally friendly and economically viable choices.
