Privacy Policy

1. Who We Are

This website is operated by Shenzhen Sainsun Packaging Co., Ltd. (“Sainsun”, “we”, “us”), a manufacturer of customized flexible packaging located in Shenzhen, Guangdong, China. For the purposes of the EU General Data Protection Regulation (GDPR) and the UK GDPR, we are the data controller for personal information collected through this website.

Contact for any privacy matter:

• Email: Leolian@sainsunpack.com
• Phone / WhatsApp: +86 19129382896
• Office: Room 1303-1304, Building H, Haikexing Strategic Emerging Industries Park, Baoshan Road, Pingshan District, Shenzhen, Guangdong, China
• Factory: Building 1, XunYang Industrial Park, Jiangjun Road Section, Chayuan Village, Qiuchang, Huizhou, Guangdong, China

2. Information You Give Us

Our inquiry forms (on the home page, the contact page and the customized project page) ask for the following details so that we can quote and manufacture your packaging:

• Your name
• Company name
• Email address
• Country
• Product interest (for example retort pouches, coffee bags or roll film)
• Your message, including any specifications, quantities or artwork references you choose to include

How the form works. The form fields are assembled in your browser into a formatted message addressed to our sales team. Depending on the button you click, that message is handed to your own email client (as a pre-filled email) or to WhatsApp (as a pre-filled chat). Your website visit does not upload the form contents to a database on our site — there is no server-side storage of form submissions. Once you press send, the information reaches us as an ordinary email or message and is stored in our business email system or WhatsApp account.

If you contact us directly by email, WhatsApp, Alibaba messaging or any other channel, we hold that correspondence as well. Please do not send us sensitive personal information such as payment card numbers, national ID numbers or health data through the website forms.

3. Information Collected Automatically

Like almost every website, our hosting infrastructure records basic technical information when a page is requested:

• IP address
• Browser type and version, and operating system
• Device type (desktop, mobile, tablet)
• The page requested, the referring page, and the date and time of the request
• Security signals used to distinguish human visitors from automated traffic

This information is generated and processed by our hosting provider, Cloudflare, Inc., for the purposes of delivering pages, protecting the site from abuse and denial-of-service traffic, and monitoring performance. We use it in aggregate; we do not use it to build advertising profiles.

We also use privacy-focused, cookie-free analytics (Cloudflare Web Analytics) to understand which pages are read and roughly how many visitors we receive. This reporting is aggregated and does not identify individual visitors.

In addition, we keep a simple first-party record of which pages are viewed and how long each page stays visible, so we can improve our content and follow up accurately on enquiries. This record is linked to a random identifier stored in your own browser (localStorage, not a cookie) and is not connected to your name, email address or phone number unless you choose to send us an enquiry. We derive your approximate country, city and network operator from your IP address, and we store only a truncated network segment of the IP address (for example 203.0.113.0), never the full address. We do not sell this data or share it with advertising networks. You can reset the identifier at any time by clearing your browser's site data.

4. Why We Use Your Information

• To answer your inquiry, prepare quotations and discuss specifications, materials, artwork and samples
• To produce and deliver your order, and to handle after-sales and quality matters
• To maintain our business relationship and keep a record of what was agreed
• To protect the website against spam, scraping abuse and malicious traffic
• To improve our website content and performance using aggregated statistics
• To meet accounting, tax and export-compliance obligations

We do not use your information for automated decision-making or profiling, and we do not send marketing newsletters unless you ask us to.

5. Legal Bases for Processing (GDPR)

Where the GDPR or UK GDPR applies, we rely on the following legal bases:

• Consent (Article 6(1)(a)) — when you choose to submit an inquiry to us. You may withdraw consent at any time.
• Contract or pre-contractual steps (Article 6(1)(b)) — when we prepare a quotation, sample or order for you.
• Legitimate interests (Article 6(1)(f)) — keeping our website secure and functioning, and handling normal B2B communications. We balance these interests against your rights.
• Legal obligation (Article 6(1)(c)) — retaining invoices and trade records as required by law.

6. Cookies and Similar Technologies

Advertising measurement (Meta Pixel). This website loads the Meta Pixel, a measurement tool provided by Meta Platforms, Inc. (Facebook and Instagram), on every page. For visitors from the EU/EEA and the United Kingdom, measurement is switched off by default (consent revoked) and only activates after you accept the consent banner shown on your first visit; if you decline or leave the banner unanswered, the pixel stays blocked and no advertising cookies such as _fbp are set. Visitors from other regions do not see a banner and measurement loads normally. It records that a page was viewed and sets cookies such as _fbp, so that we can see whether our own Facebook and Instagram advertising brings visitors to this site, and so that our ads can be shown to people who have already visited it. If you are logged in to Facebook or Instagram, Meta may link the visit to your account. The pixel does not receive the contents of your inquiry, and we do not send Meta your name, email address or message.

You can block or delete these cookies at any time in your browser settings, and you can limit interest-based advertising in your Meta ad preferences (facebook.com/adpreferences). Blocking the pixel does not affect your ability to browse this website or to contact us. You can change your banner choice at any time: clear the stored preference for this site in your browser settings and the banner will appear again on your next visit. If you submit an inquiry through the form on this website, the details you enter (name, company, email, country, product interest and your message) are delivered to our sales inbox and processed by a third-party form-delivery service solely so that we can answer your request. We do not sell, rent or share this information with anyone else, and we keep it only for as long as needed to handle your inquiry.

Our hosting provider may set strictly necessary security cookies — for example a challenge cookie issued when Cloudflare screens a request it believes may be automated. These are required for the site to function safely and cannot be switched off through the site. You can block or delete cookies in your browser settings; essential security functions may then behave differently.

Links that take you to WhatsApp, Instagram, Facebook or Alibaba are ordinary outbound links. Those platforms may set their own cookies once you arrive, under their own privacy policies.

7. When We Share Information

We do not sell, rent or trade personal information. We share it only where necessary, and only with:

• Hosting and network security providers (Cloudflare, Inc.) — to serve this website and protect it from abuse
• Email and messaging providers — to send and receive business correspondence
• Meta Platforms (Facebook / Instagram) — when you choose to contact us through WhatsApp, and as the provider of the advertising measurement pixel described in section 6
• Freight forwarders, customs brokers and inspection agencies — only as required to ship your order
• Professional advisers such as accountants and auditors, and public authorities where we are legally required to disclose

Service providers act on our instructions or under their own legal obligations. We do not permit them to use your information for their own marketing.

8. International Transfers

We operate from China, and our service providers operate globally, so your information may be transferred to and processed in countries other than your own, including China, the United States and the European Union. Where personal information protected by the GDPR is transferred outside the EEA or the UK, we rely on appropriate safeguards such as the European Commission’s Standard Contractual Clauses or an equivalent lawful transfer mechanism. You can ask us for more detail about the safeguards we use.

9. How Long We Keep Information

• Inquiries and quotations that do not become orders: up to 24 months from our last exchange, after which they are deleted or anonymised
• Customer order, quality and shipping records: for the periods required by contract, export documentation practice and Chinese accounting and tax law
• Server and security logs: for the short retention periods applied by our hosting provider

If you would like your inquiry correspondence deleted sooner, see the next section — we will do so unless we are legally required to keep it.

10. Your Rights

If you are in the EEA, the UK or Switzerland, you have the right to: access a copy of your personal information; have inaccurate information corrected; have information erased; restrict or object to processing; receive information you provided in a portable format; withdraw consent at any time; and lodge a complaint with your local supervisory authority. We do not carry out automated decision-making or profiling.

If you are a California resident, you have the right to know what categories of personal information we collect, the sources and purposes, and the categories of recipients; to request deletion or correction; to obtain a copy of your information; to limit the use of sensitive personal information; and not to be discriminated against for exercising these rights. We do not sell or share personal information for cross-context behavioural advertising, and we have not done so in the preceding 12 months.

Visitors in other jurisdictions (for example Canada, Brazil or the Middle East) may also have rights under local law; contact us and we will assist.

11. How to Exercise Your Rights

Email Leolian@sainsunpack.com with the subject line “Privacy Request” and tell us what you would like us to do. Please include the email address or company name you used when contacting us so we can locate the record.

We respond within 30 days, or within one month where the GDPR applies (this may be extended by up to two further months for complex requests, and we will tell you if that happens). We may ask for information to verify your identity or your connection to the inquiry. An authorised agent may submit a request on your behalf where local law permits.

12. How We Protect Information

We use reasonable technical and organisational measures, including HTTPS encryption across the site, access controls on our business email and systems, and the edge security protections provided by our hosting provider. Please note that ordinary email and instant messaging are not end-to-end encrypted in transit to us, so treat them as you would any business correspondence and never send sensitive financial or identity documents through the website forms.

13. Children’s Privacy

This website is intended for business and trade buyers. It is not directed at children under 16, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, contact us and we will delete it.

14. Links to Other Websites

Our site links to external services such as our Alibaba storefront and our WhatsApp, Instagram and Facebook pages. Those sites are governed by their own privacy policies, and we are not responsible for their content or their handling of your information. Please review their policies before providing personal information there.

15. Changes to This Policy

We may update this policy to reflect changes in our practices or in applicable law. The revised version always appears on this page with a new “Last updated” date. Where a change is material, we will make that clear on this page.
