"The beauty of a product begins with its packaging." This is a widely circulated saying in the cosmetics industry. Packaging is not only related to the visual appeal of the product, but also directly affects the brand image, consumer experience and even environmental impact. Among the dazzling array of cosmetics, hose packaging has become one of the preferred containers for daily chemical products such as skin care products, toiletries, toothpaste and sunscreen due to its portability, sealing and squeezability. This article will take you to an in-depth understanding of the manufacturing process, material selection, technology trends and environmental protection practices of cosmetic hoses.
1. Main types of cosmetic hoses
There are many types of cosmetic hoses, which can be roughly divided into the following categories according to structure and material:
Single-layer plastic hose: common PE material, suitable for products with low barrier requirements.
Multi-layer co-extruded tube (ABL/PBL): made by co-extrusion of multiple materials, with stronger barrier properties, suitable for products rich in active ingredients such as lotions, sunscreens, and ointments.
Aluminum-plastic composite tube (ABL): The aluminum layer has extremely high barrier properties and is suitable for products with high requirements for light blocking and sealing.
Metal hose: usually used for cosmeceuticals or sensitive formulas, with both pharmaceutical-grade stability and recyclability.
2. Detailed explanation of the manufacturing process
The manufacturing process of cosmetic hoses covers multiple precise links from raw material selection, tube embryo molding, printing and coating to tail sealing molding.
1. Raw material preparation and ratio
Common raw materials include polyethylene (PE), polypropylene (PP), ethylene-vinyl acetate copolymer (EVA), etc. Multi-layer tubes may also involve materials such as aluminum foil and adhesives. The material ratio determines the flexibility, barrier properties and cost of the hose.
2. Co-extrusion or injection blow molding
There are two common ways to form the hose body:
Co-extrusion molding (for multi-layer tubes): different layers of materials are fed synchronously through multiple extruders and co-extruded into tube embryos through the die head;
Injection molding + extrusion blow molding: some hoses are produced separately from the injection molding head and the extruded tube body and then assembled.
3. Printing and coating
The following processes are often used for the surface patterns of the hose:
Offset printing/screen printing: suitable for monochrome or basic patterns;
Thermal transfer/cold stamping: enhance visual levels and high-end texture;
Digital printing: suitable for small batch and customized production trends.
To enhance the texture, the surface can also be coated with varnish, matte oil or tactile oil, etc.
4. Sealing and capping
According to the use requirements of the hose, the tail can be:
Straight sealing (suitable for ordinary pastes);
Special-shaped sealing (more brand personality);
Embossed date sealing (add batch and anti-counterfeiting functions).
Automatic capping after sealing to ensure airtightness and ease of operation.
3. Material innovation and environmental protection trends
With the increasing global environmental awareness and the urgent need for sustainable development, the cosmetic hose industry is undergoing a profound transformation of material innovation and environmental protection transformation. As the first impression carrier connecting products and consumers, hose packaging not only bears the functions of protection and convenience, but also becomes an important symbol of the brand's practice of social responsibility. Material innovation and environmental protection trends are becoming the core driving force for the upgrading of the industry.
1. The rise of green and environmentally friendly materials
In recent years, traditional plastic hoses have faced the dual challenges of environmental regulations and market pressure. The pollution problem caused by plastic waste to the ecological environment is becoming increasingly serious, prompting companies to accelerate the search for alternative materials.
Bio-based Materials
Bio-based materials are derived from plants or other renewable resources, and typical representatives include PLA (polylactic acid), PHA (polyhydroxyalkanoate), PBAT (polybutylene adipate), etc.
This type of material has good biodegradability and can be decomposed in natural environments or industrial composting conditions, significantly reducing the lasting burden on the environment. At the same time, the physical properties of bio-based materials are also constantly improving, meeting the requirements of hoses for flexibility, barrier properties and printing adaptability.
Ocean Recovered Materials
Ocean plastic pollution has become a global focus. Using recycled ocean plastic to make hose materials not only achieves resource recycling, but also demonstrates the brand's environmental responsibility. This type of material is specially treated to ensure product quality while reducing environmental impact.
2. Design for Recycling
Material innovation not only focuses on environmentally friendly materials themselves, but also emphasizes the recyclability of packaging design. Traditional composite hoses are often made of multiple materials stacked together, which are difficult to separate and recycle, resulting in resource waste.
Single-material hose design
By using a single type of plastic material to make hoses, such as PE or PP, the hose as a whole is easy to recycle and reuse. This design reduces the complexity of the recycling process and improves the purity and utilization rate of recycled materials.
Modular structure design
Some brands use a design that separates the hose from the cap and nozzle to facilitate consumers to classify and recycle. Even a replaceable liner design is introduced, where users only need to replace the inner core, and the outer shell can be recycled to reduce packaging waste.
3. Reduction and lightweighting
Reduction is one of the important strategies for environmentally friendly packaging. By optimizing the hose structure and material ratio, the overall weight of the packaging can be reduced.
Material thickness control
Use advanced extrusion and molding technology to reduce the wall thickness of the hose and reduce the material consumption while ensuring strength and function.
Hollow structure and composite technology
Innovative hollow wall structure or multi-layer material composite method, taking into account lightweight and barrier performance, improve the environmental protection attributes and user experience of the product.
Lightweight not only reduces the consumption of raw materials, but also reduces transportation weight, reduces carbon emissions, and achieves environmental benefits throughout the life cycle.
4. Environmentally friendly printing and decoration technology
Printing inks and surface treatment are also important links in packaging environmental protection.
Water-based and UV environmentally friendly inks
Water-based inks reduce volatile organic compound (VOC) emissions, and UV inks cure quickly and have strong adhesion. They are all green printing materials and meet environmental regulations.
Solvent-free coating technology
Use solvent-free coating technology instead of traditional solvent-based coatings to reduce environmental pollution and operational safety risks.
5. Exploration of intelligent and environmentally friendly packaging
With the development of intelligent manufacturing and digital technology, soft tube packaging has begun to incorporate intelligent elements, such as smart labels and QR code tracking, to enhance the added value and sustainable management of packaging.
Intelligent traceability
Consumers can learn about the environmental protection information and recycling methods of products by scanning the QR code or NFC tag on the packaging, and enhance environmental awareness.
Circular economy system
Enterprises cooperate with recycling agencies to establish a soft tube recycling and reuse system to achieve closed-loop management from "design to recycling".
6. Industry cooperation and standard setting
The realization of environmentally friendly packaging is inseparable from industry collaboration and standard specifications. Cosmetics companies, packaging suppliers and recycling companies are actively cooperating to promote the standardization of green packaging materials and formulate unified recycling and reuse specifications.
Green certification system
Certifications such as the EU's ECOCERT and the US's Cradle to Cradle have prompted companies to adopt more environmentally friendly materials and processes to enhance brand competitiveness.
Policy-driven
Many governments around the world have introduced policies to reduce plastics and recycle them, forcing the industry to accelerate transformation and promote the research and development and market application of environmentally friendly materials.
4. Quality Control and Testing
High-quality hoses not only require exquisite appearance, but also need to pass a series of rigorous testing processes, including:
Thickness and size consistency testing;
Barrier performance testing (such as water vapor transmission rate, oxygen transmission rate);
Drop test and extrusion life test;
Color consistency and printing fastness testing;
Microbial residue and cleanliness testing (especially important in skin care and medical categories).
