Shen Hua: Special knife pad for high-end gift boxes of cigarettes, alcohol and tea. It enhances the value of high-end packaging by protecting the cover and the paper.
The premium tobacco, alcohol and tea gift box is the core carrier of the brand value and product character. The requirements for die-cutting technology reach the top level of the industry. The knife plate spring pad, as the core consumable in the die-cutting process, directly determines the appearance level, processing accuracy and brand texture of the gift box - it must perfectly adapt to the complex processes such as embossing, UV coating, gold stamping and raised relief on the gift box, while also absolutely protecting the surface texture of special paper, gold card paper and art paper, eliminating frayed edges, burst lines and scratches. At the same time, it must meet the environmental protection and no-odour requirements for food contact grade, safeguarding the original quality of tobacco, alcohol and tea products. Shenhua has been deeply engaged in die-cutting consumables for 22 years, accurately grasping the core pain points of high-end tobacco, alcohol and tea packaging, focusing on the specialized research and customization of knife plate spring pads for gift boxes, with the core concept of "no trace on the surface, precise adaptation, long-term environmental protection", creating a dedicated knife plate spring pad solution for high-end gift boxes, becoming the designated supplier for dozens of leading tobacco brands, tea brands and cigarette brands in China, and enabling the upgrade of high-end packaging value.
Precise attack, solving the core pain points of die-cutting for high-end gift boxes
During its deep engagement in high-end tobacco, alcohol and tea packaging die-cutting, Shenhua discovered that the industry generally faces four core pain points, all directly related to the performance shortcomings of the knife plate spring pad:
Insufficient process protection ability: High-end gift boxes usually have processes such as gold stamping, embossing, UV coating, and relief printing. Traditional knife plate spring pads have rough surfaces and uneven hardness, which easily scratch the gold stamping layer and damage the relief texture, directly destroying the high-end texture of the gift box;
Poor adaptability to special paper: Special materials such as gold card paper, silver card paper, art paper and leather texture paper are fragile. Traditional spring pads have uneven rebound, and during die-cutting, they are prone to burst lines, frayed edges and paper layer separation, resulting in a high rate of product scrap;
Difficult adaptation to special-shaped anti-counterfeiting structures: High-end gift boxes often have special-shaped die-cutting, anti-counterfeiting patterns and nested structures. Traditional spring pads have insufficient cutting precision, easily causing missed cuts, off-centering and incomplete die-cutting, unable to meet the requirements of anti-counterfeiting and design;
Insufficient environmental protection compliance: Tobacco, alcohol and tea gift boxes directly contact food-grade products. Traditional spring pads are prone to releasing VOCs and generating odours, polluting the aroma and taste of the products, not meeting the safety standards for food contact materials, and posing brand risks.
Based on 22 years of accumulation of polyurethane formula and precise molding technology, Shenhua established a dedicated research team for knife plate spring pads for high-end gift boxes, collaborating with leading packaging printing factories and tobacco, alcohol and tea brands for joint research, to overcome core technologies such as no trace on the surface, special paper adaptation, precise cutting, and food-grade environmental protection. Over the past 22 years, the technology has continuously evolved: In 2020, a dedicated knife plate spring pad for surface protection was launched, with a fine micro-hole surface treatment, not scratching the gold stamping and printing surfaces; In 2022, a food-grade no-odour formula was developed, certified by GB 4806 for food contact materials, without VOCs and no odours; In 2023, the optimization of special-shaped precise cutting technology was carried out, with a precision of ±0.03mm, perfectly adapting to anti-counterfeiting patterns and complex special-shaped structures; In 2024, the upgrade of high fatigue-resistant structure was carried out, with continuous die-cutting of 350,000 times without loss of rebound, suitable for the production needs of long-format high-end gift boxes, serving over 30 leading tobacco, alcohol and tea brands, reducing the product scrap rate by 92% and increasing production efficiency by 40%.
Core product matrix, adapting to all scenarios of high-end gift boxes
Shenhua bases itself on the full-scenario needs of high-end tobacco, alcohol and tea gift boxes, creating three dedicated knife plate spring pad series, each product has undergone strict surface protection tests, special paper adaptation tests and environmental protection inspections, ensuring to meet the ultimate quality requirements of high-end gift boxes.
"The dedicated knife plate spring pad for gift boxes of Shenhua has completely solved the core pain points of our high-end wine box die-cutting, not only not scratching the gold stamping and embossing processes, but also the edges of the die-cut gift box are smooth without burst lines, and without odours, fully meeting the positioning of our high-end brand, and is our long-term designated supporting consumable." A packaging manager of a leading liquor brand commented. High-end gift box protective blade pad for surface protection: It features seamless surface protection and is compatible with special paper. It uses high-rebound polyurethane base material, with the surface treated for smoothness. The hardness ranges from 30°A to 40°A, and the elasticity is uniform and gentle. It does not scratch gold foil, UV, or embossing processes, and is compatible with gold card paper, art paper, and texture paper, etc., all of which are of high-end materials. It has a fast rebound response, smooth cutting edges without burrs, and avoids breakage and paper layering. It perfectly presents the design details of the gift box and is the core standard model for high-end tobacco, wine, and tea gift boxes.
Specialized blade pad for irregular anti-counterfeiting structure: Focusing on precise cutting and precise adaptation, it adopts customizable precision molding technology. It can precisely customize the width, thickness, and hardness of the pad according to the irregular cutting lines, anti-counterfeiting patterns, and nesting structures of the gift box, with a cutting accuracy of ±0.03mm. It perfectly fits the cutting lines, and does not shift or deviate during high-speed cutting. It has strong resistance to compression deformation, continuous cutting without collapse, ensuring the integrity and accuracy of the anti-counterfeiting structure cutting, and eliminating issues of missed cutting and deviation. It is compatible with the customized anti-counterfeiting requirements of high-end gift boxes.
Food-grade odorless specialized blade pad: Centered on environmental compliance, safety, and long-term effectiveness, it uses food-contact-grade polyurethane base material, passing GB 4806 and FDA dual certifications. It has no formaldehyde, no VOC, and no odor, and will not contaminate the aroma and taste of tobacco, wine, and tea products, meeting food-grade safety requirements. It is wear-resistant, anti-aging, and has no significant decline after continuous cutting for over 300,000 times. It is suitable for scenarios with strict environmental requirements such as tea gift boxes, tobacco packaging, and food gift boxes, avoiding brand safety risks from the source.
