The birth of the egg tray: the raw material behind pulp moulding
In today’s modern world, environmentally friendly packaging is getting more and more attention. Pulp moulding technology occupies an important position in all kinds of packaging products because of its recyclable and degradable characteristics.
As one of the most typical pulp moulding products, the quality, stability, and cost control ability of egg trays depends largely on the choice of raw materials. Understanding the source and characteristics of pulp raw materials is not only the basis for optimising product performance but also the key to improving production efficiency and economy.
The most commonly used materials and their typical applications are summarised below:
فضول کاغذ
Source: various kinds of waste newspapers, cardboard boxes, corners, and edges of paper materials.
Advantages: it is widely available, easy to obtain, and inexpensive. Its fibers are delicate and soft, suitable for egg tray products with a simple structure and moderate strength requirements.
Limitations: low fiber strength, unsuitable for transporting products with high-pressure resistance requirements.
Common applications: widely used in small and medium-sized egg packaging, supermarket delivery, and other daily demand scenarios.
Agro waste: bagasse, straw
Source: fiber by-products from the processing of sugar cane, rice straw, and wheat straw.
Advantages: high resource utilization and environmental significance.
Limitations: the pulping process is more complicated and more demanding on the equipment.
Common applications: suitable for disposable tableware such as plates, bowls, takeaway food containers, etc.
Virgin pulp: wood or bamboo
Source: processed from fast-growing bamboo stalks and wood.
Advantages: long fibers, fine moulding, good texture of the finished product.
Limitations: relatively high cost, generally used in the customized or boutique packaging market.
Common applications: some high-end egg trays, such as export fruit trays, gift box inner trays, etc., have higher requirements for appearance and toughness.
After understanding the characteristics of different raw materials, the key to transforming them into moulded egg trays efficiently and stably lies in the performance and adaptability of the equipment.
