There are only four types of cardboard stacking: single-row parallel stacking; double-row parallel stacking; Tic-Tac-shaped layered stacking stacking; multi-layer layered cross stacking. The advantages and disadvantages are as follows:
1. Single line parallel stacking
Advantages: The board can get sufficient heat dissipation from top to bottom and all around; the positive and negative turns are uniform, which is conducive to the smoothness of the board; the later bonding is sufficient.
Disadvantages: The heat in the center of the cardboard is not dissipated in time, and the surroundings of the soft people are hard; the corrugated cardboard in the lower part of the stack is also soft, and the thickness becomes thinner after compression;
2. Double line parallel stacking
In addition to the advantages and disadvantages of single-row parallel stacking, the stacking has the following advantages and disadvantages: less trays and saving storage space; the heat between the two stacks of cardboard is difficult to dissipate, causing the cardboard to be hard and soft on one side.
3. Tic Tac Toe Stacking Stacking
Advantages: The cardboard has good flatness and no warpage. Due to the special stacking method, there is a gap between the layers, and the tray is directly connected to the tray. The air circulation is smooth, the heat is evenly and quickly distributed, and the strength is better than the above two. This kind of stacking takes up less pallets and saves space.
Disadvantages: At the overlapping part of the board area of ​​2/5, the moisture can not be radiated endlessly; if the quality of the adhesive is slightly poor, the composite layers of paper are easy to crack; the amount of cardboard between different layers will be deformed by compression.
4. Multi-line layered cross stacking
Advantages: Compared with the above three types of stacking, the pallet utilization rate is the highest, the floor space is the smallest, the cardboard flatness is the best, the adhesive is slightly poor, and the glue is not opened.
Disadvantages: The heat of the cardboard is not easy to dissipate, making it soft; the corrugated height is difficult to recover, and the cardboard becomes thinner; the required strength is also discounted. In severe cases, the thickness of the five-layer cardboard falls below 4mm, and the three-layer cardboard falls below 2.5mm Other factors affecting the thickness of the cardboard are under normal circumstances).
Based on the above analysis, and from the perspective of carton quality, it is clear that Tic Tac Toe stacking is the best choice.
The Polypropylene Joint for Plastic Infusion Container is made of the imported medicalâ€class polypropylene; where the material complies with FDA rule and passes the USP CLASS VI test. Beneath the joint, itis a shipâ€shape, which will form a plastic liquid infusion bag after welding with nonâ€PVC coâ€extruded film; the top opening is the inlet for loading liquid medicine. After filling the liquid medicine, the top opening will be melted to seal with the composite cap, and then form a complete softâ€bag liquid infusion product. The joint is produced in the clean plant, with the overall plant reaching to Class 10,000 and some for Class 1,000,000. The main working procedures, such as the injection molding, inspection, cleaning, inner packing and so on, are designed and processed as per the cleanliness requirements at the partial level of Class 100 , which passes the GMP onâ€site certification and complies with the cleanliness requirements of high capacity injection medicine.
The surface of production equipment is smooth, flat, and easy to clean and sterilize, with sound corrosionâ€resistant property, and inert to make chemical reaction with packing material. The precision and sensitivity of test and inspection instruments comply with the test and inspection requirements of products.
The polypropylene joint for plastic infusion container is mainly used for the pipe of nonâ€PVC softâ€bag.
