The environmental friendliness of fruit and vegetable packaging may not necessarily affect the quality of fruits and vegetables. The specific situation is as follows:
1、 Environmentally friendly packaging may have a positive impact on the quality of fruits and vegetables Environmentally friendly materials with good breathability Some environmentally friendly paper packaging and plant fiber packaging have good breathability and can regulate gas exchange inside the packaging. This helps fruits and vegetables to have normal respiration, eliminate carbon dioxide, absorb oxygen, thereby delaying the aging process of fruits and vegetables and maintaining good quality. For example, packaging apples in unbleached kraft paper is both environmentally friendly and helps maintain a certain degree of freshness. Reduce chemical pollution Environmentally friendly packaging materials typically do not contain harmful chemicals, such as plasticizers that may be present in traditional plastic packaging. This can reduce the risk of chemical contamination of fruits and vegetables, ensuring their quality and safety. Biodegradable plastic packaging does not release harmful substances when decomposed in natural environments, and has no adverse effects on the quality of fruits and vegetables.
2、 The potential impact of eco-friendly packaging on the quality of fruits and vegetables in certain situations Relatively weak preservation performance Compared with some high-performance traditional plastic packaging, the freshness preservation performance of some environmentally friendly packaging materials may be slightly weaker. For example, the moisture resistance of paper packaging may not be as good as plastic packaging, and in high humidity environments, it may lead to faster loss of moisture in fruits and vegetables, affecting their quality. But this deficiency can be compensated for by improving packaging design, such as adding moisture-proof coatings. Mechanical strength issue The mechanical strength of certain environmentally friendly materials may not be as good as traditional plastics, and they may be more susceptible to external pressure during transportation and storage, which can damage fruits and vegetables. However, by optimizing the packaging structure and enhancing the cushioning performance of the packaging, this risk can be reduced.
