[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figure 1-4A high-strength blister tray includes a lower tray 1, with a blister tray body 4 internally snapped into the lower tray 1. A support assembly is provided at the bottom of the blister tray body 4, comprising transverse ribs 6, longitudinal ribs 7, and bottom reinforcing ribs 11. The transverse ribs 6 and longitudinal ribs 7 are equidistantly distributed at the bottom of the blister tray body 4, and are arranged in a crisscross pattern. Both the transverse ribs 6 and longitudinal ribs 7 are integrally formed with the blister tray body 4. Multiple bottom reinforcing ribs 11 are evenly distributed along the bottom of the blister tray body 4. Lateral reinforcing ribs 8 are equidistantly distributed on the outer periphery of the blister tray body 4. When the body 4 is in operation, the goods are placed on the upper surface, and the weight is transferred to the reinforcing ribs and ribs through the side walls and bottom, forming a uniform force. The cross design of the transverse ribs 6 and the longitudinal ribs 7 effectively improves the overall rigidity and impact resistance. Through the setting of the support components, the load can be further distributed with the help of the metal brackets 12 at the four corners, avoiding local stress concentration, thereby improving the service life of the blister tray body 4. The setting of the bottom reinforcing ribs 11 can significantly improve the rigidity and deformation resistance of the blister tray body 4 without increasing the wall thickness, avoiding edge warping or cracking caused by uneven force.

[0029] Specifically, the bottom of the blister tray body 4 is provided with a support component, which includes metal brackets 12 located at the four corners of the bottom of the blister tray body 4. The metal brackets 12 and positioning holes 10 work together to further enhance the load-bearing capacity. The lower tray 1 has positioning holes 10 inside that work with the metal brackets 12. The positioning holes 10 engage with the corresponding metal brackets 12. The top of the metal brackets 12 is provided with Velcro 13. The Velcro 13 allows the metal brackets 12 to be detachable, further distributing the load and avoiding local stress concentration. The blister tray body 4 and the metal brackets 12 are connected by Velcro 13. The inside of the blister tray body 4 is filled with foam blocks 5. The use of foam blocks 5 enhances the impact resistance and sound insulation performance of the blister tray body 4. The two sides of the blister tray body 4 are provided with slots 3. The slots 3 allow workers to remove items from the blister tray body 4.

[0030] Specifically, protective strips 2 are fixedly connected to the inner wall of the slot 3. The protective strips 2 provide protection for the slot 3 and prevent tearing. The blister tray body 4 is made of polypropylene. The side reinforcing ribs 8, bottom reinforcing ribs 11, transverse ribs 6 and longitudinal ribs 7 are all made of high-density polyethylene. The side reinforcing ribs 8, bottom reinforcing ribs 11, transverse ribs 6 and longitudinal ribs 7 of high-density polyethylene make the blister tray body 4 both moisture-proof and economical, making it an ideal choice for packaging materials. The metal bracket 12 is made of aluminum alloy. Multiple anti-slip strips 9 are fixedly connected to the bottom of the blister tray body 4 and between the two longitudinal ribs 7. The anti-slip strips 9 improve the stability when stacking. The multiple anti-slip strips 9 are evenly distributed.

[0031] Working principle: First, when the blister tray body 4 is in operation, the goods are placed on the upper surface, and the weight is transferred to the reinforcing ribs and ribs through the side walls and bottom, forming a uniform force distribution. The cross design of the transverse ribs 6 and longitudinal ribs 7 effectively improves the overall rigidity and impact resistance. Furthermore, the metal brackets 12 and Velcro 13 further disperse the load, preventing localized stress concentration, thus extending the service life of the blister tray body 4. The bottom reinforcing ribs 11 significantly improve the blister tray's strength without increasing the wall thickness. The rigidity and deformation resistance of the body 4 prevent edge warping or cracking caused by uneven stress. The use of foam blocks 5 enhances the impact resistance and sound insulation of the blister tray body 4. The slots 3 allow workers to remove items from the blister tray body 4. The high-density polyethylene side reinforcing ribs 8, bottom reinforcing ribs 11, transverse ribs 6, and longitudinal ribs 7 make the blister tray body 4 both moisture-proof and economical, making it an ideal choice for packaging materials. The anti-slip strips 9 improve stability when stacked.
